I'm part of both TASVideos' community, as well as the speedrunning communities. While I highly enjoy to watch practically all categories, for both TASes and real time, of Super Metroid, having them all to be published on TASVideos is a bit unneccesary.
Take Ocarina of Time as an example. I have been following its progress the past 11 years and is one of my favorite game to watch runs of. It has LOOOOOADS of categories. See a list here which includes most of them:

They are interesting to have and enjoyable to watch. But many of them are just "for fun" categories and some aren't really taken serious by the community either. Some are just very arbitary, but a portion of the community enjoys running it and want it to be kept, even though new discoveries made them obsolete.
TASVideos want to track the "more serious" categories, with rules that make sense. Clugging it up with the 22 "beat-the-game" categories of OoT will just be confusing and weird. Even though each and every one of them could be an interesting watch. I see 100% Map as a "for fun" category, just like "Spore Spawn%". As none of these will practically never be in a run otherwise. But that isn't enough of a reason to publish it.
