I would prefer to have source based one first.

Ideally we'd have some way to mark binary packages with new EAPI and 
have FEATURES flag like 'prefer-binary' and go with -bin in case there's 
|| ( ) dependencies list, regardless of the original order in virtual. 
This way everyone could be happy and not choose one workflow over another.
