I think you are veering your argument the wrong way. While Views and Votes are relevant when deleting questions the most important factor is the quality of the answers.
When deleting a question the first concern you have to occupy with is: do this answers worth my time? Are they really good answers? Those it leave the internet in a better state that it was found? (the last one is a wording of one of the goals of SO, or more like SE proper)
The only thing that is included in the help center about where you should not delete is:
Before voting to delete, please check that there are no good answers; if so, then the question should be flagged for moderator attention as a potential merge candidate. We don't like to lose great answers!
Note, it says "good" and "great", which are subjectives so YMMV.
This means that I shouldn't take into account views or votes? No, it means that views and votes is not really the most important value of a post, but answers. The most pressing reason not to delete a question are the answers they produced, views and votes should be in second plane.
Now my personal take is: views and votes just means they are popular, not that they are particularly useful and shouldn't sway my decision to delete a question.
