And I think that would commit us to keep C++03 forever, which is
untenable. Further, I think expecting the minimal maintenance required
to add "-std=c++03" if a project needs it is not unreasonable.

I'd grudgingly delay the switch if someone came along with a real plan
to do that kind of upgrade on the things they cared about -- on a
specified timescale. But otherwise a sane default is more important
IMO.

Cheers.
