There's also /usr/share/locale/locale.alias, but on GNU/Linux system to
which I have access it doesn't have any information for the eo or
Esperanto locales.

You mean, the patch I proposed in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=57531#64?  For that to
work, we need to make 'locale-info' pseudo-encoding override what
locale.alias file says, I presume.

That was suggested, yes.
