Let’s add the following to each of the *-no-vendor-prefix rule READMEs but change “properties” to the appropriate construct for the rule:

“The fix option can automatically fix all of the problems reported by this rule. However, it will not remove duplicate properties produced when the prefixes are removed. You can use Autoprefixer itself, with the add option off and the remove option on, in these situations.”
