That’s my opinion, anyway.
It’s worse on alloy frame guns, where the harder steel or titanium cylinder contacts the aluminum alloy lug.
I don't know how mine compare with others but my Sc/Al J-frames (340 & 360) have the least amount of overlap between the cylinder face & the frame lug.

My aluminum J-frame M638 seems a tad more generous in it's overlap. (All are new revolvers with little use/firing.)

Neither compare to the steel frame 66-8's overlap & solid contact between the two pieces though.

Going forward, as s&wchad suggested, I think if owners of theses revolvers would take a bit of care when ejecting spent cases, & limit pounding on the ejector rod when doing combat drills, damage to the frame lug can be lessened/eliminated by contact with the cylinder.

That's what I plan on trying to do anyway.
