I'll leave this to Herbert as I am also not clear on this point. None of
the 8.8.1 boot packages should be relying on Cabal 3 syntax in their
.cabal files so I'm not sure what specifically gives rise to this

Cabal 3 does change quite a bit. In response to the number of requests
to get this un-stuck I put in some work [1] this week and last to start
the upgrade. Indeed the process is non-trivial and requires touching a
lot of code.

Nearly all of this churn is due to the removal of the Text typeclass in
favor of the Parsec and Pretty typeclasses. These changes are generally
quite mechanical but do take time.

I am quite willing to handle the uploads as part of the release process
if this is the direction we decide to take.
