point has seven questions with almost as many tag definitions. It has been used to mean restore point, mounting point, wireless access point, and location on an image. There were no examples of data point, although that would also fit. The tag has no definition and its varied usage eliminates any value as defining a category.
Recommendation: eliminate this tag so people will use more specific existing ones. access-point and wireless-access-point already exist. Tags related to data points or locations on an image are probably not necessary.
I agree with Robotnik's comment about using the existing mount and restore tags without creating additional tags for those now. Since all uses are covered by existing tags, I've edited the question to just eliminate point.
