Whatever ISPs default to deploying now will become the standard to which application developers develop.

Changing the ISP later is easy.

Changing the applications is hard.

Let’s not bake unnecessary limitations into applications by assuming that tomorrow’s networks in homes will necessarily 
be as simple as today’s.
