Hmm.  The current report is about shared catalogs (pg_shdepend and
pg_database were reported as problematic) which pg_type is not, so I
doubt that this bugfix will have any impact in a problem vacuuming
pg_type.

I'm interested in seeing a more detailed report from you about the
pg_type vacuuming failure.

Yes, in my opinion we would backpatch it, back to 9.1 even.
