Comment (by RJVB):

 I checked the history on my Mac, and can no longer say with certainty what
 happened there; it turns out the main port was NOT updated (`port:qca was
 at 2.2.1_1) but the subports were.

 HOWEVER, I simulated the botched upgrade to 2.3.4 by increasing the
 version and removing the epoch after doing a `port destroot` and copying a
 file from one of the qca-qt5 subports. That caused the upgrade to fail
 like it failed for everyone using the stock port:qca : at the activation
 stage after the actual installation of the "new" version.
 Then, I reverted the version back to 2.2.1 and restored the epoch. The
 port upgraded perfectly to 2.2.1_0, as predicted by my previous post.

 I think thus that there is indeed no reason to restore the revisions as
 they were before any upgrade to 2.3.4 .

 If somehow there are a few users for whom the old qca/Qt4 2.2.1_0 port(s)
 get reactivated instead of a fresh install, they should get rev-upgrade
 errors or else runtime issues in the dependents. Normally I'd prefer to
 avoid exposing even a few users to that, but in this case I prefer not
 exposing everyone else to a probably unnecessary upgrade (no matter how
 trivial that may seem).
