Well until you deal with email deliverability issues, which are staggeringly widespread and random. Email were great to send quick patches between friends like you'd exchange a USB key for a group project. For a project the size of Linux? It doesn't scale at all. There is a reason why Google, Meta, Red Hat, and [insert any tech company here] doesn't collaborate by sending patches via email.
