Let's see - From my past experience, Gettext reviews take forever and
the project also releases super rarely...
So I'm not sure if this will yield a solution in a reasonable amount
of time (but I'll be happy if I am surprised!).

Maybe have that emitted as another validation hint? That would
actually be nice, so users learn about it and you don't get so many
bug reports about missing features.
For the locale stuff, I'd need to have a look at how locale are done
in appstream-glib, but most of them are handled explicitly there by
clients I think, so you might be fine, except for locale matching code
(which I adjusted in libappstream to work with either BCP47 or POSIX).
The question is: Is it worth the effort? Which tool is using
appstream-glib that will also realistically receive new metadata that
was generated using the corrected locale names? (all tools I know
either use libappstream or read XML directly via some XML-loading
library like libxmlb).

Cheers,
