Adding a "Too Narrow" close option

Question

For multiple recent questions, people have wanted to close a question because the question was too narrow - not enough variety of potential answers to make it interesting.

Those questions were: Sign that word!, , and Fibonacci in +!()[]script.

The desire for such a close reason has come up before, leading to Too trivial Close Vote, where the clear most upvoted option was adding the following:

Too Narrow

1. Would it be possible to add this close reason, or is there something preventing us?

To address the question of whether such a close reason is necessary, I don't think there's currently a pressing need (although I certainly wouldn't oppose creating one, if it was demonstrated that there would be a significant benefit in adding this close reason). The community already seems to do a pretty good job of handling these on its own (all of these links require 2k+ reputation to view, as they have been deleted by various PPCG users; suffice to say, none of them are very interesting challenges).
