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. 

Virtualized installations do not cause issues and are still allowed using, for example, pipx or raw venvs.
