For what it's worth, under the hood tangled is extremely similar to this approach. Personally as just a random person in the community I've been building an appview for tangled that lets you interact with it as if you were just using git format-patch + git send-email + some MUA. You can conceptually treat the tangled lexicon as a schema for encoding a git patchset based mailing list into IPLD/atproto records and vice versa. Doing this is slightly lossy but only barely. Otherwise it's pretty seamless.
