Do you want every other package in the tree depending on glibc, and
therefore trying to pull it in on a prefix system?  (For those
unaware, prefix depends on a non-Gentoo glibc for the system call
interface.)  There are probably a few ways you could do it, but if you
got rid of the implicit @system dependency then you'd need to handle
situations where @system is something non-traditional and ebuilds are
likely to do it wrong.

Agree with mgorny's suggestion that anything required by PMS could be
pulled in by the package manager, perhaps in an EAPI-dependent
fashion.

Oh, @system has another use I didn't mention - getting rid of some
chicken-and-egg issues during the initial install.  That can be
addressed by providing pre-built stage1/2/3s, having package sets and
scripts for their building, and so on.  Maybe make world a world.d
directory with Gentoo providing a starter file and users modifying
their own addition, but being free to remove items and depcleaning
them.  Or provide a syntax for world to remove packages pulled in by a
distro-provided world, etc.  Many elements of this would benefit from
public comment obviously should we choose to go along this road.
