I agree with @OliverFendt that this license is OSD-conformant. Also, this license is found in major Linux distros such as Fedora. See e.g. https://src.fedoraproject.org/rpms/python-matplotlib

I have now created a Fedora issue for this license indicating it is allowed under Fedora's scheme. https://gitlab.com/fedora/legal/fedora-license-data/-/issues/535

Looking at https://matplotlib.org/stable/project/license.html, I think this may be PSF-2.0, with replaceable text taken into account?

By Jove, I think you're right!

It is related to the PYTHON SOFTWARE FOUNDATION LICENSE VERSION 2 but below the license for versions 1.3 or later of Matplotlib there is still the license of prior versions. Additionally I think it is wrong to determine that MatPlotlib is licensed under PYTHON SOFTWARE FOUNDATION LICENSE VERSION 2. The license steward of PSF-2.0 is the Python Software Foundation, for Matplotlib it is not the Python Software Foundation, it is the Matplotlib Development Team In my opinion these two topics qualify for an extra license

@OliverFendt I believe the license for earlier versions of matplotlib is also a match for PSF-2.0, just with JDH's initials instead etc.

Saying that the license identifier corresponding to this license text is PSF-2.0 doesn't imply anything about who manages a project or repository that uses the license. But where a license text is substantively the same as a license that is already on the license list, we wouldn't add another separate identifier if it is substantively identical. This is described for instance in the guideline for replaceable text in the SPDX Matching Guidelines.
