Git uses a decentralized model where clients/servers are blurred and really only matter if you choose to create a "central" node of git as part of your workflow but you do not have to.

More importantly, the significance to me is that it does not require any software other than git, which means I can use this approach independent of any git-hosting service. Especially moving between git-hosting services, it would be nice to have a standard way to operate pull requests.

I believe their docs cover the scenario of reviewing someone's code by pushing your review to the git repo, and others can use `git appraise list` to see open pull requests.

A trivial git-hook could be setup for automating email notifications: https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks

EDIT: add link to git-hooks docs.
