From funtoo to gentoo

Finally switched back from funtoo to gentoo after 2 years.
Git-based portage tree, concept of the flora overlay and flavored profiles are really nice & cool ideas!
However, outdated portage tree is a pain in the ass for me… :-(
Guys, why not just importing everything from gentoo portage, patching whatever you need to patch, and mask whatever you need to mask?
GCC-4.7.4 and 4.8.1 are too unstable? Just do not keyword or simply mask them. But let them be in a tree.
