Web accessibility score improvement? (lawsuit risk reduction?)

[Cameron Elliott]

I just ran one of the main web accessibility tools on the mdBook docs site, like this:

https://wave.webaim.org/report#/https://rust-lang.github.io/mdBook/

Clicking that will produce a web accessibility evaluation report.

The report states:

• 1 Errors
• 2 Contrast Errors
• 1 Alerts
• 1 Features
• 18 Structural Elements
• 90 ARIA (Elements)

I believe if the Errors, Contrast Errors, and Alerts were fixed,
that page (and others) would be considered "accessibility error free".

Are there others who see moving mdBook output toward "accessibility error-free" as a useful goal?

If so, maybe the next step is a new issue for each item?

It might be worth noting in the US there is a lot of lawsuits happening related to
web page accessibility.

Thanks
