In order to package some of the certbot DNS plugins, there are a
couple of dependencies that currently aren't packaged for Debian.
I'm happy to do the leg work for their initial packaging, but I wanted
to check in to see if you'd be willing to have them maintained by your
team in terms of updates, with the Let's Encrypt team acting as an
uploader to help out here and there.
Specifically, the packages are:
python-cloudflare (RFP: #888799)
python-dns-lexicon (RFP: #888800)
python-tldextract (RFP: #888801)
Let me know!
