But the system catalogs *store* that metadata. Whether the user's
metadata is changing or not in a high-level sense doesn't prove much
about what's happening to its low-level representation.

I prefer "realistic" :-). It is probably true that with an adequate
amount of effort directed towards upgrade issues we could make upgrading
less painful than it's usually been for PG. (I didn't say "zero pain",
mind you, only "less pain".) But where is that effort going to come
from? None of the key developers care to spend their time that way;
all of us have other issues that we find more interesting/compelling/fun.
Unless someone of key-developer caliber comes along who *likes* spending
time on upgrade issues, it's not going to get better. Sorry to be the
bearer of bad news, but that's reality as I see it.
