Python Software Foundation License

Hello,

I want to update the elasticsearch-curator package.
upstream has built in another dependency, namely cx_freeze.
https://github.com/marcelotduarte/cx_Freeze/blob/main/LICENSE.md
This has a PSF license
NOTE: This license is derived from the Python Software Foundation License which can be found at https://docs.python.org/3/license.html#psf-license-agreement-for-python-release

According to the cx_freeze maintainers, the same license as for Python was used, since cx_Freeze came out in the early days of Python.
Can cx_freeze be used with this license in Debian, so is the PSF license DFSG compliant?

best regards, 
Karsten
