Indeed, exceptions are a bit like const: us it everywhere
or not at all. We all agree to be const-correct, but:

- failure to use const correctly is diagnosed by the
  compiler, failure to use ES (exception specs) isn't.

- the std lib is const-correct, but almost only the
  language support part (memory allocation, EH) uses
