With the beta already out, I think we have released it, for some
admittedly-small value of "released". I think it's too late to make
non-pg_upgrade-able changes on mere speculation that they might be a
good idea.
In any case, I would've expected we'd end up changing all these page
formats if we go over to your concept of a metapage for everything.
Fixing indexes that already have some kind of metapage will surely be
trivial compared to fixing heaps.
