the architectural objections to base64+JSON are on record in a
submitted draft (draft-moccia-dkim2-deployment-profile) - parsing cost
at scale, loss of streaming with constant memory, opacity in
operational logs. Those are design concerns, not implementation feedback.
As implementer:
Parsing cost is negligible IMO and less error prone than the usual
relatively ad-hoc syntax around email data (e.g. MIME).
If you are an implementer and want logging to be more readable than
having base64 blobs, you're free to invent your own log format based on
decoded base64/JSON. Logging formats are out of scope for DKIM2 IETF
documents, I'd think.
Memory use seems negligible to me. I've got a proof of concept of a
streaming implementation of recipe rewind for bodies, but with current
servers, the simpler approach (having two adjacent versions in memory at
the same time while verifying) is also quite doable even for modern
large mails.
