I'm quite annoyed by announcements like this. To be complete, you have to provide a complete solution. It's really annoying with GCC that you have to check in multiple places to see which features a given release supports.
You are right. The thing is though that you (or third parties) can implement missing library features that do not require compiler support [1], but for the language itself you have to wait for the compiler. For example, thanks to the hyperproductive STL [2], MSVC has always had a fairly up to date library, but the compiler lagged behind.
[1] For a long time libstdc++ lacked regex support, but people could get them from boost and mostly didn't care.

[2] Stephan T. Lavavej, not the library :)
