That's a circular reasoning, because we didn't yet decide to have
threads be a required feature.

As for making that decision for Emacs 27: I'm not sure we have enough
experience yet to do that.  So far, only one serious application is
attempting to use threads, and that application is not yet on master.
We need more experience, IMO, before we are ready to make that
decision.
