Both these problems can be solved if and when spammers start forging

There are two problems with this scenario. Spammers won't forge
HELO names if it doesn't improve deliverability and big ISP's don't
care what small providers say.
However, the customers of big ISPs will care what the customers of small
ISPs say. At least if the latter have the guts to reject the big ISPs'
bad practices. And they have to, or otherwise we're never going to solve
the e-mail abuse problem.
