We have had some discussion before about whether software recommendation questions are on topic. This meta question is not about software recommendation questions.
Rather, I want to pose the question of whether questions about development of software which may be useful in worldbuilding would be on topic. As an example, I present you What is the most efficient data-structure to store planet elevation? which was closed by community vote during the site's private beta period. Two of those who closed the question (Tim B and myself) subsequently were appointed pro tem moderators on the site.
My feeling was at the time and remains that this type of question is a poor fit for this site because it is not a type of question that a worldbuilding expert would be expected to be able to answer. Depending on exactly how you frame it this is a software development, computer science or geographical information sciences question; it is not a question about how to make a world work.
As such, this type of questions are likely a better fit for the Geographic Information Systems Stack Exchange (because it is essentially about the design process of a geographic information system) or the Programmers Stack Exchange (because it is about algorithms and data structure concepts).
How does the community feel about this type of questions? Do we want them to be on topic? Can they be on topic? (Please provide a good rationale beyond what essentially amounts to "I think we should cater to everyone's needs in everything that can be peripherally related to worldbuilding because I think it makes for cool questions".)
In the specific question mentioned as an example, replace the concept of "worldbuilding" with "map-making in the real world"; would you still feel the same way about the question? Because the question in that case remains essentially the same: what data structures would be a good choice for storing a particular type of data? If you feel differently about the question in that case, please explain why.
Let's hash this out.
