I think the idea is promising but I'm pessimistic that those who need it most would opt-in. It sounds like a valuable project: good luck.
Thanks. It is clear that most organizations don't want to invest effort in doing what is right. If there is some ready-to-use extension/service that is proven to help, maybe we can convince the browser developers to include it in their default installation.

Any browser that decided to do this would quickly find themselves out of business. Free will exists for a reason. Attempt to circumvent it at your own peril.
