Good point. I think it's unfortunate that it isn't used more.

The good side is that even if "languages" are introduced, this var won't 
necessarily need renaming.

Perhaps we should have entries like ("\\.js\\'" . 'js-lang) in 
auto-mode-alist and then map the symbol to the specific major mode in 
major-mode-remap-alist. But for this to be useful to determine the 
language of a major mode via reverse lookup, all/most programming 
language modes will need to be featured there, rather than this being 
optional and used only for custom overrides.
