This breaks custom Vue rules - not sure if officially supported - but it was working in past.

In 10.6 and before you could create your own rules by using defineTemplateBodyVisitor from 'eslint-plugin-vue/lib/utils/index.js'.

But this is no longer available in the package.
Meaning you can no longer create your own Vue Template related rules.
