Icelandgimmick binds like this can be rarely useful for certain input dense tricks, but generally it is recommended to just get used to "normal" actions, as this will give you much more granular control over the timing of each input. for example, you have 5 frames to get an extension on your hyper/super, and having control over when exactly that jump is inputted is vital for optimizing your movement, and many strats hinge on getting an early/late extension to make them work. by using a button like you described to get a jump immediately, you eliminate all of that control. it might not matter much to you right now, but as you get better, this would be a massive roadblock and you would have to change how you play the game. best to avoid that situation.
for an example where a gimmicky bind can be useful however, a dash+jump button is a common bind among high level runners, but it is almost never used to input an instant hyper/super, like you might think. it is more useful for jumping, and then ensuring a buffered dash out of that jump. for example to input 1 good ultra (jump for extended hyper -> buffer downdiagonal dash out of the hyper) where a strat demands it, or for walljumping off a moving block and dashing immediately after to get a double boost with consistent positioning.
runs must be performed on an unmodified up-to-date vanilla client, so by extension skin mods (or any mods) are not allowed
i do agree skin mods would be a cool way to add some expression to your own runs, but allowing modded clients would make verifying the legitimacy of runs a lot more difficult
short answer: doesnt affect IGT, but you should probably correct it anyway for different reasons.
solution: go to the steam betas for celeste and set it to "beta-1.3.3.0 - v.1.4.4.0 (FNA)" and see if that fixes it.
long answer:
for the sake of in-game time it actually doesnt matter compared to the 60fps timer, but the entire game and its physics are running at 61fps instead of 60fps, which does make a small difference in how the game feels (essentially the game is ever so slightly faster and therefore more precise at 61fps). this also ends up making a RTA difference, but again, IGT is unaffected, thankfully.
this isnt really that big of a deal on its own, but the worst effect of it is that the modded client runs at 60fps usually, so if youre running modded with practice tools on 60fps, and then do your runs on vanilla on 61fps, thats pretty bad since youre playing on different game physics which, at a high enough skill level, will definitely impact your ability to develop muscle memory and consistency.
