It could if enough people would play it. But People are not into alt glitch and even less into Tofu stuff unfortunately.
Tofu takes some investment to be played well even for Tofu%. It would be too long I guess.
It would be allowed but there are the keyboard A key to skip the replay and go to next level, S key to exit level skipping the replay.
So no need to bind both jumps on the same button.
I had something like that on a very old PC that had a poor graphic card
Yeah it's a known thing and it's called a storage jump. When you die or finish a level, your character's position is kept in the game's memory. When you start next level, you start with that same position for one frame. For example : if you were touching a wall when dying, you'll restart the level in a walljump position. If you don't touch anything when dying/touching bandage girl, it won't work.
Nice you found that by yourself
For example, if your game is running but you're on your browser, when you alt, it will alt on your browser. Not in the game.
Alt works on 1.2.5, you can even do the ceiling clip. It works differently but it works.

Je le connaissais que par son pseudo mais ça fait bizarre à apprendre. Toutes mes condoléances à tous ses proches.
