Well, they have held back some slop in CPAN (a surprising place to find slop) [1]. Some of said slop recently caused GNU coreutils test suite to fail [2]. Surely the bot will get it right one day, right?
Python being a dependency of portage is gentoo's original sin. They have no business calling anything slop with how portage is coded. Truly the epitome of throwing bricks from a glass house.
