Changes between Initial Version and Version 1 of Ticket #51498, comment 8

initial	v1
9	9	* What happens if users install `p5.22-whatever` (and `p5.22-whatever` is "selected") and then `p5.22-whatever` gets `replaced_by` `p5.24-whatever`. Will `p5.24-whatever` still be selected?
10	10
11		* I'm generally slightly worried about the fact that the registry doesn't change if (default) variants change. I probably never revbump ports after changing default variants. I thought that worked properly out-of-the-box.

I thought that worked properly out-of-the-box: the buildbot builds a binary with new variants, so those who install the port from scratch do get the right thing, while "port upgrade outdated" on installed ports won't fix variants even if the port gets revbumped.
