Every game has a dynamic number of ways to beat it. For Super Metroid, that is every single combination of:
13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, and 100% that beats the game. And yes, I say "every combination of 100%" because you can collect all 100% items in different ways. And, that's assuming you plan out your route for each of those items and collect them in the most optimal manner. That doesn't even consider arbitrarily long routes where you maximize the distance between any two upgrades, for example. And THAT doesn't even consider wait times.
There are literally an infinite number of ways to complete Super Metroid (or any other game). Allowing infinite combination on this site is a fool's errand, (or, as Samsara called it, suicide).
The entire reason that branches exist, and the reason those branches are judged on optimality of route as determined by gameplay time (and not in-game time), is so that different types of gameplay following the same general rulesets can co-exist.
Once again, nothing is preventing you from creating a TAS in your preferred niche category. Its ability to be published is determined by the judges here based on the site's category rules, not by the rules of the community that surround the game.
(And, once again, it's overflow, not underflow.)
I am still the wizard that did it.

<scrimpy> at least I now know where every map, energy and save room in this game is
