Would it make sense to have this instead

ThreadFactory.virtual(Executor scheduler)

I do think .virtual(scheduler) reads a bit clearer than
And you effectively convey that you can only schedule virtual threads.
If you at some point add new thread types that need a scheduler you
can always use the same trick.
