Python

Is there a reason why the python3 version in TW has not updated from 3.8 to 3.9 or 3.10? The TW repositories have had 3.9 for a while and now also have 3.10. Is there a schedule as to when TW updates the python3 version? I would have expected it to have been updated by now considering the rolling distribution... Would you recommended against installing 3.10 now and changing /usr/bin/python3 to point to it?
