That's what I ended up doing recently on 10.6 when
trying to update macports after a very long period with
no updates. I think that the existing instructions make
a lot of sense when moving from one version of macOS to
another (with macports up-to-date to start with),
because the versions of all the ports and their
dependencies wouldn't have changed, but if the versions
of installed ports no longer exist, or if the
dependencies have changed a lot since the last update,
then just installing the requested ports, and letting
the current dependencies sort themselves out, is a good
approach.
