Sure, no one likes "What key is this completely diatonic pop song in", or "what is C-E-G-A♯", or their million uninspiring counterparts. But the close reasons we have seem to expressly forbid "chord/key ID" -style questions, on the grounds that they are "basic analysis".
What about questions that are about identifying chords or keys where the circumstances render it above "basic analysis"? Like some complicated chord, or a song with a hard-to-define key? Are these on-topic? For example, if someone asks what chord D-G-A-C is (which would have answers going into explanations much more advanced than "these are the notes, so this is the chord symbol") ?
They also mention the notion of "not being useful to future readers". How useful are we talking? Is this an absolute reason? Could questions that have use to future readers but are about key identification be allowed?
I guess my question is: Which should take priority: Clear exclusion of a topic or the reason behind that exclusion when determining topicality?
