I completely missed the fact that we should add the same rule for JSON and CSS.

[arendjr]

Nice!

I agree the same rule would be nice to have in CSS and JSON too, but I would consider that out of scope for this PR :) Ideally it would have the same name too then, so users only need to configure one rule.

I have some reservations about the severity of the rule

[Conaclos]

We don't need a such rule for JSON. Because JSON accepts a curated list of escaped characters. Other escapes are errors.
