Surely the reason that failures are so hard to mint is the “multiple ways to pass” approach that WCAG took? 
(And I’m obviously saying this with plenty of hindsight! I didn’t think of this at the time.)

If there are 3 techniques to pass an SC, the absence of one of those techniques cannot be a failure.
If a failure must always be a failure, there cannot be another way to pass. 

The more technologies (e.g. ARIA) there are available, the more ways there are to pass, the harder it is to create new failures.

I like the idea of warnings, or at least some way to say ‘this is a common way to fail’ without it being absolutist. 

It could also provide more context about the technology, e.g. ‘if ARIA is part of your Accessibility Supported list, then if is a failure not to use landmarks for 1.3.1’.

Cheers,
