The dh_python2 manpage definitely suggests otherwise:

dh_python2  tries to translate Python dependencies from requires.txt
file to Debian dependencies. Use debian/pydist-overrides or
--no-guessing-deps option to over‐ride it if the guess is incorrect. If
you want dh_python2 to generate more strict dependencies (f.e. to avoid
ABI problems) create debian/python-foo.pydist file.


The guess was correct, just not strict enough. Hence I tried using the
pydist file.

I cannot find a description of what should be in a
debian/pydist-overrides file. I tried just moving the pydist file, and
that seemed to work.

For completeness, I have debian/pydist-overrides containing:
lxml python-lxml (>= 3.3.1)


Thanks very much for your prompt and extremely useful help :)
