Hi!

While rebuilding the python related packages against the Python 3.15rc2 version
we found that python-aiohasupervisor fails to build from source:
https://debusine.debian.net/debian/r-python-python3.15/artifact/4856678/

From the log, the error seems to be:

E   DeprecationWarning: 'typing.ByteString' and 'collections.abc.ByteString' are deprecated and slated for removal in Python 3.17
E: pybuild pybuild:485: test: plugin pyproject failed with: exit code=4: cd /build/reproducible-path/python-aiohasupervisor-0.6.0/.pybuild/cpython3_3.15/build; python3.15 -m pytest -k "not test_homeassistant_info" -W "ignore:'asyncio.iscoroutinefunction' is deprecated:DeprecationWarning"
I: pybuild base:385: cd /build/reproducible-path/python-aiohasupervisor-0.6.0/.pybuild/cpython3_3.14/build; python3.14 -m pytest -k "not test_homeassistant_info" -W "ignore:'asyncio.iscoroutinefunction' is deprecated:DeprecationWarning"


Please note that while we ran into this error during the rebuild against Python
3.15, that doesn't mean that the root cause for the failure is necessarily the
new Python version.

Setting the severity to important for now. Once Python 3.15 is released and
later added to python3-defaults, this bug will become release critical.
