You're right, but in `LaTeX-arg-usepackage' style file is loaded by
`TeX-arg-input-file', so before you insert options.  At that point for
`babel' there are no active languages, except if you set languages as
global options.  That's why I've suggested to reload style file for
any package if there are options.

I'm sending a git patch with your suggestions.  Thank you!
