I tend to dislike the term "limp-wristing", as the underlying problem often experienced by some shooters has more to do with a less-than-firm grip and an unlocked, or "broken", wrist occurring at exactly the wrong moment during the recoil cycle. It's more of a grip stability/support issue than just a "limpwrist" issue.
As a firearms instructor and armorer I've had more than ample opportunity to see an occasional pistol & shooter combination which just didn't allow for consistently optimal functioning because the shooter couldn't sufficiently stabilize the frame during a critical moment of the recoil cycle. It's happened with shooters using plastic framed pistols, as well as metal framed pistols.
This lack of grip stability usually "robs" force from the recoil spring, and/or doesn't allow the slide to make its full rearward (or forward) run/travel at the proper speed. Feeding requires proper "timing" of the slide run and its cycling, which includes returning & locking the slide & barrel into full battery after stripping, feeding & chambering a round.
Weakened recoil & mag springs, improper lubrication or and/or even fouled magazines can sometimes also be involved, exacerbating the potential for it (shooter influence) to occur and
become an issue, as could low powered or over-powered ammo.
Think of it as a Venn Diagram, with the shooter-influence being one part of the diagram, which could interact with other influences to different degrees.
I've seen some folks who couldn't
deliberately induce a grip-stability related stoppage no matter how hard they tried, and some folks who
couldn't consistently prevent one from happening no matter how hard they tried.
Sometimes it seemed to involve a particular type of pistol, or just the wrong caliber/ammo/pistol combination. (The caliber/ammo combination could speak to the recoil force involved, or perhaps the "dwell" time of the recoil impulse acting within the shooter's grasp.)
I remember one shooter who was involved with agency T&E for a number of different pistols. One range session there was a particular large plastic framed .45 with which that shooter experienced repeated feeding stoppages. All the other shooters that day had no problems with that gun, using that ammo ... and that shooter had no problems with other model guns, including in the same caliber (same ammo). The .45 ran normally for shooters immediately before & after that shooter, but not for that shooter. The shooter had to really work to get a solid grip and locked wrist for the gun to work normally. Everyone else had no such issues.
Sometimes it's seemed to involve a shooter performing something out of the ordinary, distracting them from having the same attention to their grip technique. They seemed unable to grip, support & stabilize the frame in the manner to which they normally accustomed (meaning not shooting the gun slowly, standing in a balanced, comfortable position and using 2 hands for slow-fire shooting).
Other times it seemed to only happen when the shooter was shooting while moving, and their grip support, and their hand & arm positioning, wasn't consistent. Or, when they were using some cover/barricade and they unintentionally let the gun contact the cover during recoil/cycling, affecting their grip support and wrist lock.
If this potential shooter-related condition wasn't something that could occur (and be corrected), it probably
wouldn't be listed as one of the probable causes of feeding problems and other stoppages in so many different pistol armorer manuals by gun companies who do a lot of LE/Gov business & sales.
FWIW, if someone has to stop and
think about their grip technique's consistent firmness (not milking it, readjusting, etc) and their locked wrist support for each shot, then it's not hard to see how they might become distracted and lose their focus on the grip when stress or unexpected physical exertions are required.
Train & practice until you can't do it wrong.

Then hope the world doesn't throw something unexpected at you which can degrade or interfere with even your trained and ingrained responses.
Short-stroking pump shotguns or revolver DA triggers is something that even trained & experienced shooters may have happen to them at an unexpected moment, in inopportune circumstances. Not hard to see someone potentially failing to sufficiently grip and support a pistol which is
recoil-operated during live-fire.
