Oh, you are right, sorry! I misread the code. I though
TensorProductsCategory was a subclass of
RegressiveCovariantConstructionCategory. Hmm, back to the discussion
about option (a) or (b). The same question arises for
CartesianProducts; do we want it to be regressive, like is the case
of Quotients and the like. It's not exactly the same use case.

Cheers,
