You originally said "because its not needed" but didn't explain why. I
wanted to make sure there was no loophole. I'm not trying to make any
other point, just checking.

Forgive me for being dense, but what is there to stop you using a
CopySnapshot in TopMemoryContext? If you did, there would be no way to
free it, nor would we notice it had been done, AFAICS. Not anything I'm
thinking about doing, though.
