I think that since many subtransactions cases are no longer becoming
edge-cases these days, we needed to improve that and it might be
helpful for users to mention it. How about the following item for
example?
Improve logical decoding performance in cases where there are many
subtransactions.

I've seen we had such item, for example in PG14 release note:
Add a test module for the regular expression package (Tom Lane)
But if our policy has already changed, I'm okay with not mentioning
the xid_wraparound test in the PG17 release note.
