Something I didn’t see listed was the lack of a package manager for protos.
For example if I want to import some common set of structs into my protos, there isn’t a standardized or wide spread way to do this. Historically I have had to resort to either copying the structs over or importing multiple protoc generated modules in my code (not in my protos).
If there was a ‘go get’ or ‘pip install’ equivalent for protos, that would be immensely useful; for me and my colleagues at least.
