MarsSeed  filed a deletion request for python2-corner :
As python2-sncosmo has been deleted, this helper module has no use anymore on AUR.
Supernova Cosmology packages support Python 3 only, so there is no point in keeping defunct Python 2 libraries around.
So I suggest deletion. AUR has the Python 3 variant of this and of sncosmo.
Request #36022 has been Accepted by muflone :
[Autogenerated] Accepted deletion for python2-corner.
