The problem is that the exact serialization choice is up to clients -- there
isn't one facility, like there is for Formula. The motivating example is
Nullability inference, where we'll be serializing to custom protobufs. So, I
don't think that C++'s encapsulation mechanism is a good fit here.
I'm open to alternative designs -- e.g. should we consider defining a protobuf
message here, etc.
