There is no robust accessibility linter tool (axe covers only a portion) and you don't want to add ARIA attributes to all HTML markup. Both "accessible" and "responsive" are ultimately subjective, and all code gen tools I've used are more than happy to introduce startling a11y regressions.
It'll probably get there eventually, but today these are not things solvable with context.
Like:
- When making CSS changes, make sure that the code is responsive. Add WCAG 2.0 attributes to any HTML markup.
- When making changes, run <some accessibility linter command> to verify that the changes are valid.
etc.
The non-dev doesn't need to know/care.
