I think you've convinced me that while it is surely easy to write a
server-side envelope synthesizer, it looks hard to write a high-quality
and robust server-side envelope sythesizer.

You've also convinced me that even if submitting envelope parameters
ends up being nominally optional, any client i work on would always
explicitly send them anyway because i'd be afraid of whatever bugs lurk
inside whatever server-side synthesizer i happen to be talking to.

So from an implementer's perspective, i don't really care about making
the submission envelope parameters optional, and would happy if JMAP
ends up requiring the client to provide them during submission.
