The main problem I see is that if it's becoming a real incremental (across all config layers) it would change behavior for users as they'd need to prefix their use-expanded vars with -* to retain their current config. But I guess that's why you added that final clause about profile scope.
I'd gotten the impression that users would have to do that anyway once flameeyes gets his ALSA_CARDS expanded, what with all the cards that were going to be on by default anyway. Weren't there some other variables in make.conf that were going to behave this way at some point? Though it'd be nice to have this done sanely; for example, configuring X turns off most everything for the user already; no need for "-* nvidia vesa" for example, it's a minor thing to add, long as users get sufficient warning.
It's a pretty simple fix for the documentation, too, long as we know what docs would be affected by all the expansion and incrementing goin' on.
