It's a worthwhile goal but it's practically impossible to get it right.
For example, right now we've had quite a few cases of Python ebuilds
wrongly declaring <stabilize-allarches/>, i.e. people missing use of C
besides Python.

That is, unless you can figure out a way for Portage to reliably detect
SOURCETYPE and tell people what to set.
