Regarding no sprint during swimming script, it's typical devs always have unfinished left overs within the files or background. It's up to us modders to fix what they have scrapped.I tried to implement this in QOL Constants, but it's a bit buggy, due to there being no "Sprint" State while in water. But you can press the Sprint button while swimming to toggle a loop of the alternate animation on or off. (There's also a "Dolphin Dive" button.)
Resident evil 1.5 for example. I think there is puppy swim animation in Saints row 2 but I didn't re-check to see if that was mandela effect. I didn't check for long time and is lazy but I can check. I release a trainer which anyone can find the value for all animations in-game just I am lazy and do not mod sr2 no longer.
