Surely what makes HTTP different from RPC is that HTTP is a
networking protocol, RPC is a moniker which describes a style of
network computing. Another way of saying this is that the HTT
protocol is a linguistic abstraction for enabling and framing the
distribution of hypertext. RPC identifies a pattern or style for
distributed computing but is not itself a language for computing.
Sorry to be a pedant, but RPC and HTTP are as apples to oranges. 

The controversial matters seem to be 1) whether this HTTP language
has interesting utility beyond distributed hypertext; if so, how to
evolve the language? 2) whether the RPC style of distributed
computing is limiting our ability to solve problems; if so what
styles are appropriate?
