The reason we added it is that it's what ANALYZE does, and a big
restore bloats pg_class without it.

I don't think those are major concerns for v1, so in principle I'm fine
removing it. But the problem is that it affects the documented
semantics, so it would be hard to change later, and we'd be stuck with
the bloating behavior forever.
