I haven't heard anyone demand that JMAP support every SMTP extension.
That would be ridiculous -- no SMTP or submission server supports them
all, either.

But what we do need is an architecture that can pass through whatever
extensions the server wants to support, without needing to revise JMAP
each time there's a new extension.

Those of us who apply DKIM signatures would be very unhappy with that
misdesign.  Sure, an MUA on a phone isn't likely to do that, but
consider my example of list management software running through JMAP,
they do it all the time.
