While I agree with everything else you said there, I don't believe 
either of these are true, unless by 'implies' you mean that's how you 
usually do it. I have done a lot of work with non-zero VMIN and/or VTIME 
in non-blocking situations, and I've done non-blocking with different 
approaches to delivery.
