Comment (by kencu):

 Thanks. The way MacPorts handles upgrading default variants is in need of
 some fixing. There is an open ticket in the 4000 series about this that I
 don't have time to reference right here, but this issue has drawn
 attention in the past month as a problem.

 I recently made some changes to how cctools works to try to prevent this
 kind of thing happening, so I will look at the ld64 port to do the same.

 For now, obviously, don't try to install {{{ld64 @3_3+ld64_274}}} on 10.15
 as it is not meant to work there.

 The solution, to paraphrase from what I did in cctools, is to not even
 make that ld64_274 variant visible on 10.15, and then it disappears from
 history.
