Thanks Ian for your insight!

So it seems this is pretty much the only sane way around this.

This would also be the case for us.

Mh, in our case we have this entry:
    Tests: pytest
    Depends: diffoscope, python3-pytest
    Restrictions: needs-recommends
If I go down the route of autogenerating d/tests/control I could simply
drop the (as Paul pointed out, unreliable) needs-recommends restriction,
and have all the recommends spelled-out in the Depends field.


Do any of the diffoscope contributors have any hard feelings on me
making d/rules yet longer and implement the above?  It would end up with
another bit to update whenever a new debian relations in added in the
external_tools, even if done semi-automatically...
