My take: I am for it, or at very least to give it a try, following the path
you suggested.
I use pylint in a few other projects and it saved me from some bugs
and led to improvements.
IMO it is worth its price.
While I'm waiting for more acks/nacks, could infra add "pylint" to our
Jenkins slaves?
Regarding Nir's on-gerrit comment: I'd like to have pylint run by
default in order to avoid adding new pylint-detectable bugs. If we do
not add a pylint_blacklist now, I do not believe we'd ever make it
empty.
