+2 to that, there are a bunch of technologies that could replace the 
rabbit+rpc, aka, gRPC, then there is http2 and thrift and ... so a 
writeup IMHO would help at least clear the waters a little bit, and 
explain the blocker of the current RPC design pattern (which is 
multidimensional because most people are probably thinking RPC == rabbit 
when it's actually more than that now, ie zeromq and amqp1.0 and ...) 
and try to centralize on a better replacement.
