Yeah, you're absolutely correct. This thread is a part of the overall
work on the transition to XID64 in Postgres. As far as I remember, no
one explicitly raised concerns, but it's clear to me that it won't be
committed as one big patch set.

Here is a WIP patch @ 8191e0c16a for the discussed above issue.
I also had to merge several patches from the previous set, since the
consensus is to use the PRI* format for outputting 64-bit values, and a
separate patch that only changed the format with cast and %llu lost
it's meaning.

If this option suits everyone, the next step is to add a part related
to the pg_upgrade.
