Yeah, obviously. But if one implementation adds it, it becomes a lot more
likely that others do it too. I also suspect that libstdc++ may also really
like this.

I don't know, but IMO it would even be worth just adding it in ABIv2 if we can
get it as an extension. I expect this to bring a _lot_ of improvement in terms
of compile times and debug binary size.
