Hello,

I'm using vue-i18n on my nuxt app with typescript.

I have a simple question :
Why in

declare module 'vue/types/options' {
	interface ComponentOptions<V extends Vue> {
		i18n?: {
			messages?: VueI18n.LocaleMessages
			dateTimeFormats?: VueI18n.DateTimeFormats
			numberFormats?: VueI18n.NumberFormats
			sharedMessages?: VueI18n.LocaleMessages
		}
	}
}

`local

Tried posting a comment that was very long, just got "could not paste comment".

Is your feature request related to a problem? Please describe.
When importing a file, some labels are skipped but without knowing which ones

Describe the solution you'd like
At the end of the import, have the list of skipped labels (and as a bonus, the reason)
