This has to be done via a GLEP rather than going straight into PMS.

The problem with the way Portage does it is that it lets sets be
specified that run arbitrary code using Portage internals, including
code using internals that aren't stable between Portage releases. You'll
need to come up with a new design that doesn't have any of that
nonsense, and then get Portage to implement it.

As soon as you introduce them, people will want to use sets in
profiles/ files.
