It's dying of old age.

On a more serious note, I think the basics are pretty solid - both the
theory and the code (which mostly builds on what was introduced by the
CREATE STATISTICS thing in PG10).

I'm sure there are things to fix, but I don't expect radical reworks.
There are limitations I'd like to relax (say, allowing expressions
etc.), but those are clearly PG12 stuff at this point.
