gRPC protocol was designed to build high performance, cross platform and usable libraries for building microservices. It was designed on top of HTTP2 to explicitly make use of
Many of gRPC features work well only on HTTP2 semantics. While implementing gRPC on top of HTTP1.1 downgrade is feasible, such implementation would lose many of gRPC advantages of efficient usage of network resources and high performance. It would add significant complexity across multiple language implementations and would have higher bar and complexity for implementing and testing interoperability across these implementations. We have also relied on adoption of HTTP2 which has been very rapid and hence the ecosystem is also evolving rapidly to support HTTP2 features. We have also relied on proxies to provide this functionality to allow http1.x only ecosystem to work with gRPC. Such support exists in many proxies (nghttpx, linkerd, envoy) and is coming to others like nginx..Hence we have not implemented gRPC on HTTP 1.x.
