api design – GRPC Services: Central Proto Repository or Distributed

We plan to keep a central proto repository to keep all proto definitions and its generated code here. We would keep messages as well as service definitions in a central Git repo. We plan to drive API design standard from this central repository.

But, any service which want to use this to expose a sever service or generate clients would have to import from this repo (.pg.go).
Do you see any issue with this approach? Or do you see keeping service proto files individually in the service repos as a better alternative.

PS: Starter in the GRPC journey of building microservices. Still learning the right way to structure and distribute code here.
