Error about "python.packaging" missing despite it being installed

[KucharczykL]

Hello,
on Tumbleweed I get the following error:

Compressed release-notes-sled-15.5.20230104.tar to release-notes-sled-15.5.20230104.tar.bz2
/usr/lib/obs/service/set_version:33: RuntimeWarning: install 'packaging' to improve python package versions
  warnings.warn("install 'packaging' to improve python package versions",
At revision 22c938d10c553eaf36d1f2a3e1a889b3.

However, python310-packaging is installed:

# sudo zypper in --no-recommends python310-packaging 
Loading repository data...

'python310-packaging' is already installed.
No update candidate for 'python310-packaging-22.0-1.1.noarch'. The highest available version is already installed.

Nothing to do.

Importing packaging.version modules works, except for LegacyVersion:

Python 3.10.9 (main, Dec 08 2022, 14:49:06) [GCC] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from packaging.version import parse
>>> from packaging.version import Version
>>> from packaging.version import LegacyVersion
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'LegacyVersion' from 'packaging.version' (/usr/lib/python3.10/site-packages/packaging/version.py)
>>>

Could it be related to LegacyVersion being removed in https://github.com/pypa/packaging/blob/main/CHANGELOG.rst#220---2022-12-07?
