Deletion of Non-canonical spells in Harry Potter

Comment: Completeness? I don't think so. Wikipedia is an encyclopedia of useful content, it's not a matter of "let's jam in every minor detail just so it can be complete". If it's useful and notable enough for other articles: I can see this information moved elsewhere. But if not: it just goes, and doesn't get resurrected as cruft. I know   just fine, so don't go throwing links at me
