Hi! First of all, I'm not a Gentoo dev but a proud Gentoo user and also a developer of a piece of software that's present in portage tree under app-lc/ category, and Gentoo is kind of tier-1 distro for me.
I'm currently considering using C++14 in my project, particularly features that aren't supported by gcc 4.8 and are barely supported by 4.9 [1], but the standard is already fully supported by clang 3.4 [2]. Thus I wonder how bad is actually depending on recent clang in ebuilds? I ask because depending on the outcome of the discussion I'll either start playing around with C++14 in, say, only new modules that aren't present in the tree yet (most likely I guess) but are good candidates for inclusion, or postpone that until gcc like 4.10 is released (less likely but most "safe" I guess), or happily start using all new nifty C++14 features in the existing codebase as well (extremely unlikely :)).
