[math] MATH-852

[Sébastien Brisard]

Hello,
As expected on such hot issues, it's difficult to arrive at a consensus
among committers. However, I think that this ticket might be useful for
contributors (or even committers, I would be first!).
So the question is: what do we do about this ticket? Are there some more
"rules" we would like to discuss?
Best regards,
Sébastien
