Certainly not a "first priority", but a higher priority than fixing tall
stacks, yes perhaps.

I did a rewrite of fstk to use pf, and, well, it was non-trivial, since
the APIs are rather different. We (I and Greg) decided the effort was not
worth it, since fstk should be nuked anyway.

Well, there are a lot of chicken and egg problems here. Basically anywhere
you start is good, and I won't put up a fight about your starting
position. But replacing old defunct code should be high on the list of
things to do. Especially that old and klunky fstk - but that one is tough.

Anyway, ai_unit_goto() could perhaps use pf easily. Check out
ai_unit_execute_path() in aitools.c.
