GCC 4.8 is three years old.
I don’t think we should put a three year hold on all current and future C++ language features.
Vendors that want to ship security updates to old, stable OS’s should maintain a branch that cherry-picks fixes from trunk and applies build fixes as necessary, rather than holding back development in trunk.

I don’t think that shipping trunk as a security update on very old platforms is a viable strategy.
