Inbound GRPC will be limited to HTTP1.1; that's a limitation of the platform rather than the language runtime. We're working on HTTP2 support, but I can't promise any timelines.
By inbound GRPC you mean when running an app engine instance as a client right? So running a GRPC server is completely out of question still I would presume?
I mean running a GRPC server, yeah. It's a limitation of our networking stack which we're working on fixing.
Hi (App Engine PM here) You can use any go package in the Go 1.11 runtime, including the ones relying on GRPC. Did I answer your question?
You cant run a GRPC server though still right? Thats all I really want to be able to do especially now that the app engine endpoints libraries are no longer supported on python
