The real issue is of course false binary compatibility promises made

Of course it's quite hard to do right, especially with C++, but still
I'd expect "core" libraries to do better here...

KDE/Qt can apparently do it for C++ (there is a suitably large rulebook they
use), so why can't GNOME do it for C (which needs a lot less rules)? It feels
like GNOME software is intentionally wanting to be annoying.

Perfect bug report - especially since the last comment is not about
GNOME, but about libxcb running into same issues - talk about 'core

'underlying systems' like X don't get 'this right' neither.

Still, yes, it would be awesome if upstreams were less opposed to the
notion of symbol versioning, but it is soo easy for an upstream to miss
adding a new API symbol to the table that it is quickly getting messier
than it was before (especially on large code bases like glib/gtk -
where maintainers refuse the loudest).

glib basically stands with: yes, we want to do it, but only if the map
can be auto-generated from source files based on annotations. This of
course 'can' - but the respective info-extractor is not written -
nobody cared sufficiently for this to happen.
