This conversation has died, so let's wrap things up with a few parting comments:
 * SP is merely detritus from previous bot moves. Its WhatLinksHere report clearly shows it to be almost exclusively used outside the main namespace — in discussions and whatnot. Indeed, a few acronyms related to ranges are still around because they were the basis of bot moves, and they were not deleted at the end of those moves. The original acronym move was, at the time, a very complicated, multi-day affair.  A few, minor things got lost in the shuffle.  I think DAN still exists too, and is, I think, on SOTO's removal list. Existence is not the same thing as policy.
 * While I personally disagree that NOTDWU is confusing in any way, I also don't particularly care if it changes. And while there are respondents to this thread whose passion runs about as hot as "if it ain't broke, why fix it", no one seems steadfastly opposed to the notion of a change, either. Furthermore, no no one has a particularly convincing or heartfelt defense of INVALID. So we'll be going with Tangerineduel's suggestion of NOTVALID.  In fact, the switch has already happened.
 * It's important, for technical reasons, to be able to distinguish between those stories which are valid and those that aren't. NOTVALID isn't just an acronym; it's a vital hook that a bot or DPL can use to generate useful lists. COMIC, TV and the several other acronyms have the meaning "this is a story that happened in the indicated meaning and is valid". We therefore will not be polluting that message, or making it harder for automated processes to distinguish between valid and invalid stories. An invalid audio is NOTVALID. It is not AUDIO.
 * Categories are of a lesser priority, and will be changed as time permits.
