But only if a later suitable (for everything dependent on it) version is possible on every supported OS. And it would mean bumping portfiles, and rebuilding everything depending on dropped versions.  It probably wouldn't be worth the bother, and given all the constraints, might only get rid of a few versions.

so we've got 2 issues here :
    - which pythonXY the pyXY-{name} support
      and whether theese can be brought up to python37
    - whether any Portfile that demands a pythonXY that isn't python37
      can be updated to depend on python37 instead

We'll need some statistict / overview on this matter.
I'll look into this.

It's also a question about keeping the macports infrastructure up-to-date.

I've eg somehow gotten libsvm installed, and it has :
    Variants:  [+]java, [+]python27, python34, [+]tools, universal
as well as being seriously out-of-date:
    libsvm @3.20_2 -> Version 3.24, September 2019
