Are there any handlers/hooks/middlewares to work with untyped serialized request/response grpc payloads? Motivation is to do efficient signing and signature verification of request/response. Signature might be passed as metadata. Without such handlers/hooks/middlewares deterministic signing and verification is not efficient (need to serialize manually) and even not possible in general case, because proto3 standard does not guarantee deterministic serialization. We can do workarounds using libraries like this https://github.com/coingaming/signable#readme but in most cases being able to work with untyped payload is much more easier.
