[opensuse-packaging] How to properly define versioned dependencies to python-pytest

after some struggling over the weekend, I finally have my python repo mostly
back in shape again. What still bugs me are versioned dependencies to pytest.

Here's the current state of affairs:
python-pytest (aka pytest version 5) is python3 only.
This is accompanied with python-pytest4 and python-pytest3, both conflicting
with python-pytest and providing python-pytest = 3.xx/4.xx.

Let's ignore 3.xx for now.

python-pytest provides a python3-pytest.
python-pytest4 provides python{2,3}-pytest4

Tumbleweed has this prjconf in place:

# python2-pytest4 should win over python2-pytest
# python3-pytest should win over python3-pytest4 since pytest5 is python3 only
Prefer: python2-pytest4 python3-pytest4

but I don't understand, *how* python3-pytest is winning over python3-pytest4

d:l:py:backports uses this prjconf:

# there is python-pytest4 and python-pytest
%if 0%{suse_version} < 1550
Prefer: -python-pytest4 -python2-pytest4 -python3-pytest4

This results in picking python3-5.xx and python2-4.xx, if unversioned.

In my youthful(lie) carelessness, I would have hoped to find some prjconf in
d:l:py:pytest, that would deal with this issue, but nothing. doesn't cope with such
complex issues.

In my project home:frispete:python, TW seems to get this right (how?), but the
Leaps are suffering when using:

%if 0%{?sle_version} >= 150000 && 0%{?is_opensuse}
Prefer: -python-pytest4 -python2-pytest4 -python3-pytest4

While this almost does, what I want, it fails for versioned pytest requests,
which result in:

conflict for providers of python2-pytest >= 4.4.0 needed by python2-pytest-
xdist, (provider python2-pytest4 conflicts with python2-pytest)

conflict for providers of python2-pytest >= 3.6.0 needed by python2-pytest-
timeout, (provider python2-pytest4 conflicts with python2-pytest)

Although the Leaps are defined identical, 15.0 differs significantly from 15.
{1,2}, but again, I don't understand, why it is differing.

Could some brave soul shed some light on this, please?
