I really think this is something that should be discussed across all
(or at least more than 1) distro.  This change will have all sorts of
repercussions with thousands of upstreams.

Luckily there are forums and standards bodies for cross-distro
discussions of this sort.  Some of these are imperfect, a few like FSB
are mostly dead, but that's a good reason to fix those organizations,
not to go it alone.
