We discussed that in the past with Mike, and his answer at the time
was that every driver should implement that, which I did some time
ago.
However, it was before Tomeu patches, that indeed enforce constraints
at the consumer level, but I'm pretty confident we could add some
provider-side constraints quite easily.
