OK, let's try to move it forward somehow: so Piotr, you'd like numpy
pydist file to have 2 lines.

numpy python-numpy
numpy_strict python-numpy-api$N, python-numpy (>= $foo)

is that correct? as Jakub, I fail to see the advantage of the first
line, and the second one would still be generated by dh_numpy - what
am I missing? sorry, just a dh_ command less doesn't seem so much
simpler than trying to bend dh_python2 to the numpy rdeps needs.

same question as above - how much do we have to try to complicate our
lives in the pydist + dh_numpy instead of just use dh_numpy, that will
generate the correct dependencies no matter the python helper the
package is using?

If possible, we can support dhp2/non-dhp2 (see? I'm not trying to
boycott :) ) but i think there should be a real advantage of
supporting both.

I think this is the last point to tick, and then we can probably have
a reviewed solution, hopefully.
