Here's two features that by themselves are important enough to get EAPI
3 implemented. Using pkg_pretend it should be possible to eliminate
expected dies from build time and as such improving user experience. An
example is two use flags that conflict with each other. Use dependency
defaults make the life of ebuild writers easier as you don't need to be
careful with version restrictions any more if you have a case where
something has been on by default and then becomes a use flag for
example. This should eliminate cases like causing glibc downgrade in the
depgraph by being careless.
