I'll try to get you more feedback on this soon.

BTW, Google cloud already just instruct their users to ignore the
xidStopLimit HINT about single user mode:

https://cloud.google.com/sql/docs/postgres/txid-wraparound

I checked with archive.org. This directive to just ignore the HINT
appeared for the first time no later than December 2021. Fixing this
in Postgres is long overdue.
