Hmm, I thought about this for a while. And decided not do that since
setting a destination is certainly the exception not the rule, and a
very seldom exception. And we do cover this by allowing people to create
the message first, then attach the destination to it, and then send it.

In fact I recently went through the API and tried to get rid of all
parameters that I could get rid of, that I felt weren't really
necessary. I am pretty sure I don't want to reverse this...

Sorry, but this really was a concious decision.
