Comment(by febeling@…):

 Replying to [comment:3 raimue@…]:
 > Removing ports on upgrade could be bad as we also allow installation of
 ports not in the PortIndex by using the `current` pseudo-port or `-D
 portdir`.

 good point. So then ignoring them is in fact the right behaviour.

 > I can't think of a way how that could happen with the recommended `port
 upgrade outdated` as a removed port is never in the outdated set, so I
 assume you used `port upgrade installed` as gail is still in the installed
 set?

 But that's what I did, actually, port upgrade outdated. And I was just
 assuming that this was not properly handled. I will run a test and report
 later. I had the same exact behaviour later with render, which was
 removed/renamed as well, so I was quite confident that this was always the
 case with removed ports.
