 There is nothing to downgrade. I have already prevented the selection of
 clang-17 or newer as a compiler on the affected older systems.

 https://github.com/macports/macports-
 ports/blob/master/_resources/port1.0/compilers/clang_compilers.tcl#L16

 If ports then *specifically* select clang-17/18 in some way, thats their
 choice.
