They don't need to 'focus' on that, since there are various strategies to achieve it without redesigning the blockchain as a whole. For example, there are light clients [1] you can run which only download part of the blockchain and still provide some guarantees.

The only problem I have with a light client is the fact that it is nigh to the impossible to do any sort of mining at all.

I'm curious, why is it impossible? I don't know much about mining.
