As said, "auto-forward" behavior is quite popular in IDPA where you normally shoot to slide lock. I have seen many shooters so dependent on it that if the gun does not close when the magazine is hard rammed, they will bump the baseplate instead of going to the lever. That usually works, but if it does not, they are really losing time.

I think there are Glock shooters rounding the corner of the stop to promote auto forward, I don't know about MP users.

The SECOND worst thing about the phenomenon is a gun that auto forwards PART of the time and you never know what it is going to take to complete the reload.

The FIRST worst thing is that every once in a while, the slide will get ahead of the top round and close on an empty chamber. Most common in IDPA with 10 rounds in a 17 round magazine and lots of free space for the ammo to bounce up and down in.

S&W probably made the right move on the 2.0, especially in light of the Page 16 warning.
