There's quite a large population of people already using JSON for qlog,
prior to WG adoption. So far, there has been a practical benefit to an
interoperable serialization format that was strongly linked to the schema
definition by draft version. During the adoption call I don't recall there
being suggestions for dropping serialization altogether from
draft-ietf-quic-qlog-main-schema.

Wearing no hats: I think including at least one serialization format as
part of the work is a useful function to drive design and development
decisions. There might be a question about whether
draft-ietf-quic-qlog-main-schema should include the concrete serialization
or if it should be spun out to a separate document. However, I think this
question is tangential to the current call.

Cheers,
Lucas
