Is there any way to spot missing messages?

[PaulCombal]

Describe the feature

Assuming the following example:

<i18n>
en:
  apple: Apple
  pie: Pie
fr:
  apple: Pomme
</i18n>

Is there any command that would allow me to easily spot that the "pie" key is missing on the "fr" locale on that component?

This would be incredibly useful, what are the other possible solutions? Manually comparing every key of every locale on every page is too tough of a job..

Thank you

Theres an eslint rule for that: https://eslint-plugin-vue-i18n.intlify.dev/rules/no-missing-keys-in-other-locales.html
