The only thing that can parse ebuilds is bash, and it can only do that
once it already knows the EAPI. Another cache won't solve anything
since there's no way to generate that cache to begin with -- and a
second level of cache would slow things down, not speed them up.

Because all the alternatives are worse, and none of the objections to
the extension have been technical in nature. They've all been "we don't
want you to apply anti-mould paint to the rotting bikeshed because it's
only available in brown".
