When I did performance testing of mgmt a year or so ago, I found that 
JSON encoding really *is* the bottleneck in many cases - this is the 
reason why the ?columns= parameter exists, and also why it's implemented 
in terms of throwing away information just before we encode it.

But no, unless someone has a good reason for why HTTP API performance is 
a big deal for them, faster JSON is pretty low down the list of priorities.
