If we were to make a breaking change to this package, there would be other things I would like to do. For example, I would like to change this plugin to the ESLint language plugin. https://eslint.org/docs/latest/extend/languages Changing to the language plugin would allow to use directive comments such as <!-- eslint vue/attribute-hyphenation: off -->.

When I have time, I will list the breaking changes I would like to make to this plugin.
