I have to say I feel like these comments provide very limited value, since they don't tell me how the `noexcept` is strengthened. Conversely, I also rarely care whether a particular `noexcept` is strengthened or not.
I feel like there would be significantly more value in having some consistent scheme in which we test strengthened `noexcept`s, making it easy to find where we test them for a particular type/function. That would avoid comments which can easily get out-of-date and make sure we have proper test coverage for any strengthened `noexcept`s.
