MarsSeed [1] filed a deletion request for python-datafreeze [2]: I suggest to delete this Python module, discontinued in 2017. Does not properly support Python 3.6+, and its python2 subpackage is broken because of several missing dependencies. Safe to drop from AUR as nothing depends on either subpackage.
