Comment # 1 on bug 1195316 from Marcus R���ckert

TBH the clean solution is to have a provides for the other version of the name
in the package both both work.

and that provides does already exist.

rpm -qp --provides python38-prometheus-client-0.13.0-1.1.noarch.rpm
python3-prometheus-client = 0.13.0-1.1
python3-prometheus_client = 0.13.0-1.1
python3.8dist(prometheus-client) = 0.13
python38-prometheus-client = 0.13.0-1.1
python38-prometheus_client = 0.13.0-1.1
python3dist(prometheus-client) = 0.13


so my question would be rather: why does your zypper not see this provides and
installs the package?
