That's a cruel alternate universe, I would've hoped that Motif being in use by more people than just the devs of one homebrew Unix desktop would mean that we wouldn't have suffered through that much versionitis.
from 1989 to 2005 everyone used more or less the same version (from 1989) because vendors and standards are painful
it wasn't like, meaningfully standardized. just no one ever updated anything. or set a meaningful version string. you just guessed which bugs were un-fixed based on `uname`
I basically meant that we could've avoided the (needless) versionitis of gtk, the toolkit once introduced to rewrite a Motif-based application. (Never understand why they did have to reinvent the Xt part, too, but, well…)
