 Macports installation keeps offering this upgrade which is not suitable
 for and can't build on my OS version? (I mean - after multiple {{{sudo
 port clean qt6-qtmultimedia; sudo port selfupdate}}}?)

 The {{{qt6}}} PortGroup does/should pick the correct version if a port
 uses that. Having said that, if you explicitly installed
 {{{qt6-qtmultimedia}}} before the {{{platforms}}} line got adjusted then I
 am not sure. I would expect, as you imply as well, that the installation
 would bail out since you're trying to install it on an unsupported macOS
 version. If you say that this doesn't happen then your guess on why that's
 the case is as good as mine. Just uninstall it, and install the
 {{{qt67-*}}} port(s).

 > Also, I don't think Xcode-14 that you list as required for Qt-6.7
 installs on MacOS-11 - Xcode-13 is the last version that works on it
 (AFAIK).

 Nobody said that. The Portfiles and PortGroup say this:
 {{{
 set qt6::available_versions {
     qt6     {6.8   {24 23}}
     qt67    {6.7   {24 23 22 21}}
     qt64    {6.4   {24 23 22 21 20 19}}
 }
 }}}

 so macOS 11 (= darwin 20) only support {{{qt64}}}, the {{{qt67}}} port
 should work for macOS 12 and above. According to the information
 [https://trac.macports.org/wiki/XcodeVersionInfo here], that should all
 work with XCode versions.
