Maybe this is worth a bug report against Hunspell.  But is this really
relevant to how Hunspell is invoked from Emacs?  It certainly isn't on
Windows, because we inject LANG into the environment there.  But what
about Posix hosts?

Fine with me.

That cannot fly: we cannot second-guess the user's locale, and we
shouldn't force some arbitrary locale on them.  It's basically a
mis-configured system, so signaling an error is good enough, IMO.
