I haven't looked through all of them yet, but the majority of closure candidates are not on the list because they are off-topic, but because they are not constructive. For example, this question on architectural patternsarchitectural patterns is on-topic, but it's also asking for a list of things. Using a question to generate a list is not constructive. Another example is this question about what methodologies read upwhat methodologies read up on, which is far too broad and general for a good question.
The purpose of a STCI action is to fully improve the tag - remove the bad tag, retag good questions with appropriate tags, and either fix or remove bad questions from the site so they don't remain as bad examples.
If you think that you can make a heroic edit to anything on the closure list, please do so. It will get reviewed before anything happens. However, keep in mind that many have answers and that it's often better to close/delete and re-ask questions that have answers that will be destroyed/rendered invalid by a heroic edit.
