Not every question needs to be (nor could be) a Wikipedia-level-annotated, Pulitzer-winning question. We have thousands of examples of quick and dirty questions that exist in order to help somebody answer a simple question about Ubuntu.
The base question for this is an example of that. Somebody wants to know something. The original wanted numbers for a specific release but was edited (hours before you voted to close it) to ask a much more general and useful question.
In answer to your actual question (which is more about demanding statistics), see if you can answer the question before trying to close it. If you can write an answer, and explain how you came up with that answer, that's almost certainly the very best outcome for everybody involved.
Does adopting this inclusive stance mean there will be less-than-ideal questions? Sure. Does the policy alone mean there'll be an avalanche of new barely-on-topic posts? Almost certainly not. We're the only two people who read meta anyway :)
