I guess that was a joke, given the smiley, but I'll bite:
1. pg_freespacemap is intimately tied to the implementation of the FSM.
It was completely overhauled in the FSM rewrite, and there's no
guarantee it won't change again in the future to reflect changes in the
FSM implementation. And if it does, we won't bother to provide an easy
upgrade path, so existing queries using it will brake. For the same
reason it's in contrib and not pgFoundry: it's very dependent on the
server version.
2. It's not useful for the general public.
