Currently, yes that's kind of true. But it's really only considered obscure because the GIL makes it so you either have to do some weird non thread pattern or go with a different language, and people often go with a different language.

Kind of a Catch-22 of "Well no one uses it that way, so why should we make it possible to use it that way? Well, no one uses it that way because it's impossible to use it that way"
