And since we *have* abs(), how often do we need this? Adding an operator to
the language is a VERY high bar, there must be a strong reason for this. What
would it allow one to do that can't be done with the library as it is?

Operator <=> is the only operator we've added since C++ was first standardised.
It was added because the three-way comparison needed to be a language feature
so we could have the other relational operators synthesised from it, otherwise
we could have simply done with a library solution with extension points.
