So do I.

Certainly add it to 3.7.  I think the decision whether to add it to 3.6 and
the stable releases should be up to the respective release managers.  As you
say, it's not a language feature, but it's still a new feature and as such it
does fall within a gray area.

I'd personally have no problem with adding it to 3.6 and possibly earlier
stable releases, but I'm not an RM of any active releases any more.  I'd say,
open a bug, post the patch against the versions you want to see it applied to,
go through the review process, and let the RMs decide if its worth the risk.
