While I still have access to the u@g.o email, I'll respond here.

Actually you missed the mark completely.
Nothing in the tree itself specifies what shell to use - instead it's
the package manager. So the PM on Gentoo/Linux/FreeBSD *could*
be /bin/sh and on the systems where /bin/sh is not possible to change to
a POSIX compliant shell then it can still use /bin/bash or wherever it's
installed.
This also applies to the userland tools. If the ebuild or eclass *has*
to use the GNU variants then it should either adjust $PATH so that it
finds them first, or it prefixes them all with g, like it does on
Gentoo/FreeBSD.
None of this is technically challenging in itself, it's just that the
key people who would have to do the work to make this possible have
already given a flat out no.

Exactly so :)
