The credible alternative is to require only the three predicates

As a person that has written quite a bit of interval software,
I would say that subset, interior, equal, and not equal must be present.
As argued before, the others are virtually useless, and can be
created from their definition by the very rare users who needs it.
I fully agree, not very useful. I would prefer a compact standard.
IMO, PROFIL/BIAS has a nice minimal set of operations.
