Not neccesarily. ebuilds are still ebuilds, namely Unix shell
scripts. Most of my problems come from them not from emerge per se.

It does.

Portage is updated regularly. EAPI evolves. Try estimating how many
man-hours are put into it. That will give you some perspective on
man-hours needed to maintain another implementation. Make some research
on existing attempts (Paludis).

The most promising way in my amateur-ish opinion would be to localise
some task which Portage is slow at, and try to reimplement it (100%
correctly!) for immediate and hopefully long-lasting gains. At least
that could provide the project with some momentum and attention early
on.

Another attractive goal would be the ability to resolve
dependencies interactively. I'm not even where to start with this
though. Maybe if user could increase the backtracking threshold
(emerge --backtrack=n) without restarting the whole thing, that would
already be worth it, who knows. That would require lazy search of some
kind.
