I think we already do this. Its built into the fabric of the web. Not sure why we are proposing arbitrary limits and additional user opt in for this.
Wether a website wants to be inefficient or has a good reason for having a lot of resources it impacts the speed with which the site loads. The slower the site loads the more users are going to abandon the site. Stats say by 2 seconds most users have abandoned a slow loading site. Caveat that if the user feels the site is really worth the wait, they will wait longer.
So seems everything in this proposal is already addressed...
