Since I'm using a git checkout for my portfiles on that host and I was running darwin 20 when I did `port sync` after that change hit, my portindex had, for example 1.5.0_1 for zstd. After upgrading to Monterey, that means 'port outdated' thinks zstd is outdated, but trying to install it installs 1.5.0_0. (so `port outdated` still thinks it's outdated).

This was also reported as <https://trac.macports.org/ticket/63685>.

I would generally agree. In cases where different platforms need 
different versions, the approach used by ld64 with separate (sub)ports 
per version is preferable.
