What is the point of "Invalid component name" warnings?

Recently I noticed these warnings in the console.

Possibly they are relevant in some other use case, but…
I am using Single File Components, and they are included via imports, so importedComponent.name is not used. It’s either the import name or rather the property name from the importedComponent.components option.

Where are these warnings useful?

It might be helpful if you provided the related code and warning messages that accompany it.
