in emacs.spec there is License: GPLv3+ and CC0-1.0 but according to https://fedoraproject.org/wiki/Licensing:Main there is no CC0-1.0 short name. It should be CC0
Fixed via https://src.fedoraproject.org/rpms/emacs/c/0263a47ced44da16563b07f11335962a7158707f?branch=rawhide I have not rebuild emacs due to that though.
