Your post is taking an implicit "everything is optional" view. But, it does allow you to be stricter. Common Lisp Object System also touched on all of these ideas years ago.

Everything has been `optional` for about a decade.

> The option to set a field to required is absent in proto3 and strongly discouraged in proto2.

Ah, I dropped off protobuf a while back. I definitely remember a lot of uproar about it, at the time.
