Multipart is widely used in email messages where you have no idea what
software the recipient is using, much less any control over it. I do
not think it would be a good idea to invent something that is not
backward compatible.

Honestly, if you're worried about performance when generating
structured data on the fly, I'd use CBOR.

R's,
