I saw that I had some outdated ports, and did an upgrade of outdated and not openmodelica-devel.  The difficulty is that one of those ports was omniORBpy which is what would have “broken" openmodelica-devel and caused the rev-upgrade.  This is not something that would have been obvious beforehand.  And also, is not a problem by itself.

The idea that "sudo port -u upgrade outdated and not openmodelica-devel” will not only upgrade openmodelica-devel but also delete all the old version of that specific port seems like a trap to users.

The installed openmodelica-devel is now broken (won't work with the new omniORBpy). rev-upgrade /could/ ignore the -u and build a new openmodelica-devel to fix the issue for you, but you wouldn't be able to re-activate the old one and have it work.

I completely agree that there is not an obvious “correct” answer.  I understand why it did what it did, and just wanted to put this issue to the community, but I don’t claim to have a single “solution”.  
What you suggested might be the best procedure to follow going forward.
