That's the new intended behavior. I you want non-debian python packages, install them in a non-debian python via virtual environments.
The idea is to prevent installing into /usr not preventing install in $USER I hope.
According to the PEP it's both, and it actually makes sense. Python does not distinguish between packages in system-wide and user-specific locations.
Allowing non-virtualized installation of Python packages into the user-specific location could therefore break Python programs and libraries installed by apt/dpkg.
On Fedora they use the -s option for all system apps that use python to prevent breakage from user installed packages.
I have been living in that happy world where pip install --user was safe to use.
Virtualized installations do not cause issues and are still allowed using, for example, pipx or raw venvs.
I am aware of that, but don't reach for venv for simple stuff. Clearly I'm going to have to figure out how to do this for my use case now.

I think this is a major bug.

I have been using the following to add useful python based commands to my user locally:
$ python3 -m pip install --user <package>
For install I get this:
$ python3 -m pip install --user colour-text
error: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.
If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.
See /usr/share/doc/python3.11/README.venv for more information.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
This look wrong to me as I am not installing into the systems site-packages.
