I like protobuf for some use-casess (namely grpc) but a) it's a binary format and sometimes (often times) it's nice to have a text protocol b) protobuf libraries and protoc have given me way more grief overall than json (python, js, c++) If your workflow already supports it, I can see it being useful, but it's got a pretty steep learning curve to be honest, certainly more than json, despite the ill-implemented libs out there. If I wanted a binary format, IMHO I'd go for msgpack first, and reach for protobuf if that didn't work for me.
