Licence :: * trove classifers are deprecated

[Carreau]

It is replaced by License-expression (which is exclusive with license that we used, so can't just replace for now).

I don't follow this. Shouldn't we use License-Expression: BSD-3-Clause?

Yes, but we would need to remove license, but we need to check the minimal version hatching and whether it properly support License-Expression first. We can't "just add" License-Expression and expect things not to break, while "just removing" the trove classifiers will not break anything.
