Since we have custom off-topic close reasons:
...we can no longer choose the default off-topic close reason:
Should we add a new custom close reason that mirrors the default reason text, for the cases where none of the more specific reasons match? The text would be:
This question does not appear to belong here. Either it's not database-related or it otherwise conflicts with the scope of our site. See What topics can I ask about here?, What types of questions should I avoid asking? or this blog post for more info.
We should still prefer to use the custom reasons, or Other (explaining what is wrong), but having the default text available would be a useful time saver, and prevent people choosing a less appropriate close reason. A particular concern is that the current arrangement encourages migration when the question would be better simply closed here.
