According an assessment made by semlanik , the current support of HTTP/2 in Qt misses a few features which would be required to implement an HTTP server which can be used for gRPC. This is for example, a support for bi-directional HTTP/2 streaming. So, the questions are:
a) is the all what is missing to implement a HTTP server for gRPC?
b) do we need to implement these features or is anther solution possible to implement an HTTP server for gRPC
c) what else is missing in our HTTP/2 support and how do we handle this in the future
