It's not "an abomination of a workflow", and it's very possible for communities to have difficulties in scaling with a mailing list and have a bus factor of 1 despite plenty of movement on the mailing list. Git also had a git-request-pull command that prepares a mail with the same information that you can find in a pull request on GitHub even before GitHub existed. There is no "one true way" to Git and if organization to adapt their workflow to their needs they can have issues both with mailing lists and the centralised forge model.
