I would like a format string so that for my products I can choose to do
arbitrary revision's in packages based on the data present in the recipes (and
elsewhere)..

But the way I see this, you are correct.  This is an effort to help automate the
PR .= ".1" and similar, but based on checksums and system configurations changes....

To me, "PR" stays as it is used (mostly) today.  As a way to indicate revisions
of a particular recipe...  The other changes can optionally site on top of that
based on the format string that the packaging back ends will adopt.  (We can
even make the default that the packaging revision = PR as the default string.)
