I disagree that this was clearly wrong -- you just haven't seen that
future yet.  It doesn't say "it will be removed before Postgres 20" or
"it will be removed by 2025", or "it will be removed before David
Johnston comes across this documentation again".  It says "will be
removed in an unspecified future version", which seems sufficiently
open-ended to me.

We could change "will" to "might" or "may" or "could", but I think we
could also leave it well enough alone.  It doesn't actually hurt
anything, does it?

You could add a bullet point to the TODO page in the wiki to complement
it, but I don't think you would remove the doc paragraph while it at;
instead it'd probably remain redundant until we actually implemented
extended stats on joins, and then we'd remove both.
