BTW, I think the option 1 of sharing between threads might lead to
complications in some implementations, since we now have variables which
are neither global nor specific to a single thread but are shared by
some subset of all threads.

If those vars are never `setq'd, it's OK because this sharing can be
eliminated by copying their values, but since we don't have such
guarantees, it sounds like option 2 of "no sharing" is more future-proof.

We can provide ways to transfer the value (but just the value) of some
variables from a parent to his child.
