I didn't state why I suggested that, but here's the reasoning:

Unless I missed an update somewhere, USE flags are covered by PMS and 
thus available to be used in ebuilds, etc.  AFAIK, portage FEATURES are 
just that, portage FEATURES, and thus are supposed to be opaque to 
ebuilds, which shouldn't need to care which PM is running or its 
features, as long as it's PMS compliant.

Thus, the split between the FEATURES bit which the ebuild shouldn't need 
to know about (the user sets up the symlinks and sets the features and 
portage takes care of it managing the rest for existing versions without 
rewriting), and the USE flag, for where upstreams and/or ebuilds are 
actually rewritten with the possibility of both layouts (and later only 
the /usr locations) in mind and the ebuild installs to the targeted 
location based on the USE flag.
