Reviewers: If this default-flipping-befavior is ofimportance, please do note this fascinationdiscussion. This is because it is seems likea somewhat significant recognition at aprogressive time point in the review.

I think I'd prefer that the "default" interface (that is, the one that
users will likely use by default) to be the one that implements the
"right" behavior (i.e. the behavior people find most useful) and keeps
implementing that behavior regardless of the standard committee
decisions on the standard.

We recently had Boost.Scope review, and in its results it was
highlighted that people generally prefer better interfaces to strict
conformance with the standard. Boost libraries don't have to be strict
implementation of the standard, especially when we can do better.
