Hi, First of all, IANAL.
As I commented in a similar bug in Ubuntu [1], while the fix for this issue is available upstream and seems technically straightforward, it injects a deprecated python module in its code base and re-licenses it as CC0. The PSF license suggests "that PSF's License Agreement and PSF's notice of copyright [...] are retained in Python alone or in any derivative version" and that "in the event Licensee prepares a derivative work that is based on or incorporates Python or any part thereof [...], then Licensee hereby agrees to include in any such work a brief summary of the changes made to Python."
