re plaso_and_deps_updates.diff, I skimmed through it, couple of things
I noticed;

- your tree isn't up to date, there are some files from 2020 or so
in there which have been updated more recently

- py-artifacts, filenames in /usr/local/bin are getting a bit too
generic (stats.py -> stats, validator.py -> validator), can they
be renamed (or are they needed at all? i don't see them in docs)
