Good question @fbm3307, there are two cases we could theoretically cover, the rest of the complains are related to reading from your home directory (which is very hard to mock and test if you don't want to mess with your home directory), or to some filesystem errors when loading the content of the files, which is very hard to unit test as well.

Anyway, we can take a look at the two cases (when the provided kubeconfig doesn't exist, or when it's a directory) in separate PR - this one is just for dropping the field.
