Yeah, in my 20 years of using and developing on GNU/Linux the only binary compatibility issues I experienced that I can think of now were related to either Adobe Flash, Adobe Reader or games.

Adobe stuff is of the kind that you'd prefer to not exist at all rather than have it fixed (and today you largely can pretend that it never existed already), and the situation for games has been pretty much fixed by Steam runtimes.

It's fine that some people care about it and some solutions are really clever, but it just doesn't seem to be an actual issue you stumble on in practice much.
