That's because it could be done as a contrib module ;-)
(Yeah! Postgres is a very extensible database!)

I'm not sure what should be in the main and what should not.
Why is pg_freespacemap still in contrib?

I think the module is not mature yet and users will want to
modify it to their satisfaction. It will be easier if the
module is separated from the core codes. (The same can be
said for contrib/auto_explan, which is my other proposal.)

Now I'm working on storing statistics into disks on server
shutdown. If it is impossible unless the module is in core,
I would change my policy...
