It is already a public constant. And I see no strong reason to change
this (strong enough to justify breaking change).

For context, I plan to provide a global language-identifier alist that
will link human-readable language names to abbreviations like "de",
"de-de", etc. These abbreviations are not unique to LaTeX, but also used
elsewhere, so there is no guarantee that babel .ini files will always
use a consistent set of language abbreviations.

Thus, auto-generating the alist may be not reliable. At least some
manual overseeing may be needed.

But the general idea of auto-generating this alist is not bad. Patches
welcome, I think. Though I am not sure if we can easily handle tricky
cases like weird installation directory for TeXLive or MikTeX.
