Yep! That's the nuanced argument I'd look for, as opposed to 'gRPC bad, they added it because they're from google!' Simplicity wise my favorite scenario is where if I'm using Python I can pip install an interface (or maven, or NPM, etc. etc) which is the versioned, supported interface for a component. REST + Swagger can help a lot there. So can gRPC. But I can also get how your favorite scenario might be to explore a REST API and build your own client.
