Yes. This was an issue back in the Athlon Thunderbird days.
"It's on the user" doesn't work as an argument when all of your large desktop/server OEMs notice a large uptick in failure rate post-assembly.
I remember how they briefly tried those black foam sticker pads in the corners of the substrate before acquiescing and using the IHS.
At some point they realized they could do better than a heatsink mounting system that involved trying to balance a heavy metal object on a small pedestal while trying to hook a tensioned spring to a clip you couldn't see by exerting tremendous downward force with a flathead screwdriver. I guess those motherboard return rates finally got to them.
