Yes, I think that makes sense to have that, and per-request not per
Transport.  We might in future want per-Transport persistent options
too but I don't see a case for it now.

Having a syntax which guards against typos specifying options that make
sense to no Transport would be good.

Another syntax might be

 t.get('foo', t.hints(prefetch=False, ...))

where hints is a factory method along the lines of what Robert outlined.
I think that's tolerably concise.
