What will happen during upgrading if new version add a new filed in the proto, and old version received the new message? @overvenus

What will happen during upgrading if new version add a new filed in the proto, and old version received the new message?

If the old version receives the new message, it will discard new fields unless goproto_unrecognized_all is set to true. In that case, new fields will be stored in the XXX_unrecognized []byte field in binary form.

Both TiDB, PD and their tools are not using the XXX_unrecognized, making it essentially dead code, which is ok to remove.
