Yes. Done.

Ok. Done.

I agree that the code is a little bit awkward.

Yep.

I'm not either.

Sure.

Actually it would work if both are mixed: the code would aggregate a
sample. However it does not look very useful to do that, so it is
arbitrary forbidden. Not sure whether this is that useful to prevent this
use case.

Yep.
Attached v4 improves comments and moves tx as an assert.
