It’s a nice idea but I don’t know if it will help.

The history of the web is one big loop of:

1. Nifty feature that’s suitable for a wide variety of user agents, from GUI browsers to screen readers to text interfaces to automation.

2. Approximately 0.1% of web sites adopt it properly. The rest hack up something that mostly works for most of their visitors while ignoring any use case outside of a human driving a mainstream browser.

3. Automation works around it by pretending to be a human driving a mainstream browser.

4. Other cases should be handled better, so let’s add a nifty new feature that’s suitable for a wide range of things. Goto 1.

See: forms, CSS, “semantic web.” Even REST APIs mostly exist as monstrous piles of client-tied functionality that can’t be reasonably used from a client other than the company’s official apps and web site.
