MarsSeed  filed a deletion request for gnuradio-osmosdr-gqrx-git
Orphaned VCS package, last updated in 2017.
In 2018, repo has added note that this is obsolete,
as this was just for hosting patches not yet in
upstream gr-osmosdr, which at that point seems to
have gotten merged.
Safe to delete this package, nothing depends on it
specifically, only on its virtual provides that
is satisfied by other AUR packages.
MarsSeed  filed a deletion request for systemd-denotify :
Development of this Python 2 tool seems to have been
discontinued in 2018.
Package is broken because of the missing python2-systemd
package, and also because python2-notify has no source
available anymore and it's not on PyPI either.
So I suggest to delete this package. I think there can be
alternative solutions to this use case that still work.
