One argument against Protobuf is that people are already moving away
from it in favor of FlatBuffers, Google's successor to Protobuf that
doesn't require serialization/deserialization of structures.

Do we really want to be chasing the latest serialization library fad
each time a new one comes out? I do think there is value in having
accessible serialization formats, which is why I think it's a good idea
to provide custom format to protobuf conversion tools.

This way users who prefer not to include large dependencies don't have
to, and protobuf users can just do an extra step to convert it into
their preferred format.

Cheers,
Will
