rumpelsepp [1] filed an orphan request for python-can [2]:

The maintainer of this package seems overall inactive. I checked his
AUR profile and he seems inactive since the end of 2019. I
commented/contacted back in november 2019 and got no response. I would
like to adopt this package (and happily add him back as a Co-
Maintainer if he likes), since I rely on this package.
