Some new information about Babel that may be of interest to the topic of
this thread.

I have received an email from Javier Bezos (whom I know from the
Spanish-speaking TeX users' mailing list), who is the current babel
mantainer, as well as the person responsible for all the improvements
and new features of the package. Although he is not currently an
Emacs/Org user, he has been following this thread with great interest,
so I am transmitting here, with his permission, some interesting
comments from him:

[...] I am very interested in all possible improvements in babel so that
it integrates as best as possible with automatically generated files.
Among them are the possibility of using BCP47 codes or using a language
(at least basically) without the need for a prior declaration. These are
things already done, but there are others that can still be improved.

[...] any suggestion for improvement is very welcome [...]

Among the things I agree on is name issue. I am unifying the dice in the
CLDR as much as possible, and already, in fact, it is very advanced:

https://latex3.github.io/babel/guides/locale-naming.html

[...]

The ini files contain information that is not actually used by babel,
but that could be useful in other packages or even external
applications. One of them is the name of the language in English and in
the vernacular form, as they are in the Unicode CLDR. As I explain in
the link I gave you, the purpose is that the babel name is based on the
CLDR name with mechanical changes. Anyway, CLDR names are also included
in the ini files, to establish correspondences more easily.
