Q:

Should we keep [kartik-v] tag?

There is a tag kartik-v. And there are 59 questions with this tag.
They are about yii2-widget-fileinput, not the person who keeps it running.

A:

This tag doesn't add anything to questions, so I think there's no reason to keep it.
There are only 60 questions tagged, so we can just retag these question manually and this tag will be deleted by system.
Edit: there's also tag kartik.
