[Question] Fundamental question regarding protoregistry

[alwaysastudent]

I am not sure this is an appropriate place to ask, but I am wondering why would we need to register any of the descriptors into protoregistry? Sorry for this naive question, hope someone kind can explain the fundamental need for registering descriptor types into protoregistry.

They are necessary for using dynamic schemas that may contain extensions or that may contain message types that are used in payloads of google.protobuf.Any messages.

If you haven't encountered any use for them, then you are not likely doing anything with Protobuf that requires it. So maybe the shorter answer is: for your use case, you possibly don't need to register descriptors into a registry.
