MarsSeed [1] filed a deletion request for python-watchdog-git [2]:

I recommend to delete this badly configured, unmaintained VCS package
from 2015.
Chiefly because it has received exactly zero user or maintainer
attention during the last 8 years apart from mine - and I don't use
it, I was just looking for abandoned packages.

It's enough to keep extra repo's stable python-watchdog.
