I disagree that it's not TRT. Most problems are technically unsolvable
if you take into account the infinity of ways that the user could have
customized Emacs or their OS, that doesn't prevent us from solving the
“typical” case.
But I'm also fine with your proposed alternative.

Having a separate setting that governs multiple features and might allow
us to identify a user's “main” language (or something like that), sounds
useful too. While I'd prefer to rely on “the language that the user
types in”, relying on “the user's language” is a fine compromise. As
long as “the buffer's language” doesn't factor in.
