The two issues are the same.

There are lots of constraints on what the bash side can do that are
for package manager implementation sanity reasons. The whole
constant cache requirement thing, for example, is purely a side effect
of how package managers work.

We were discussing your trollish claim that I thought that things had to
be done a particular way. It is of course highly obvious that there are
several ways of achieving the desired result, and highly obvious that
there are a whole bunch of factors affecting which one works best.

As it happens, all three package managers picked different solutions,
all based upon extremely obscure internals issues. Which brings me back
to my original point -- mandating a particular behaviour to enable some
horrible ebuild hackery that doesn't even do what people want would be
a very silly decision.

Your premise is faulty. Ebuilds may not call phase functions, and
never do.

If you want a technical discussion, post using your other account with
your real name on it, not your sockpuppet. It's a bit hard to take you
seriously when you maintain two personas, one for real development and
an alterego for Pkgcore fanboyism / Paludis bashing.
