Correct.  I should have said "more likely to be deterministic"  Bitcoin Core does not rely on determinism in BIP70; I was referring to recent upstream efforts to make protobufs usable in a deterministic fashion by default.

I'm a bit confused.  It's been a long time since I looked at protobuf (and will have to dig into it soon), but I seem to recall it doesn't have any of the determinism properties you guys just said.  It is intended to allow you to skip details of the on-the-wire representations and just send a bunch of named fields between systems.  I thought there was no guarantee that two identical protobuf structures will get serialized identically...?

Thanks guys, great answers. 

The design choice certainly makes a lot more sense now regardless of whether one agrees with it or not.
