gRPC without protobuf

[pepone]

For example, gRPC's IDL is Protobuf and you'd be hard pressed to find examples of gRPC applications that don't use Protobuf.

examples of using gRPC with JSON are a google search away

I would remove the sentence.

Looking at your two articles, they actually make my point: using gRPC with an IDL other than Protobuf--such as JSON--is uncommon & much harder than with IceRPC.

I guess I could reword it: For example, gRPC's default IDL is Protobuf. Using gRPC with another IDL is doable but requires significant efforts.
