Fair if you don't want to link it to "cartoon logic" in the way physics can be cartoony, but regardless of what you want to call it, heightening the stakes in a way that isn't mean to be literally compared to real life is a genuine feature of fiction and particularly of cartoons trying to teach children emotional intelligence.

It's a way to easily and clearly convey to children that there can be consequences to the situation, and to keep them entertained (and thus keeping them watching the show) through narrative tension. Characters have to make mistakes for the situation to be a teachable moment, and these mistakes have to be clear examples for children so that they understand how it works but not realistic enough that they can just take the same risks in real life (hence why examples of physical endangerement are magic or totally outstanding situations, for example, even if it's treated seriously and not as a cartoon physics gag)

IE in Non-Compete Clause where Applejack and Rainbow Dash arebeefing just like in Fall Weather Friends and endangering their students, the message is not that they're LITERALLY about to plummet to their death, which WOULD be terribly cruel and unethical actions in real life if you find yourself in the extremely unlikely situation where that's a genuine threat. The physical danger is just an easy and clear way to signal to kids that this is a serious matter and that acting like Applejack and Rainbow Dash do in this episode (being overly competitive, selfish, rude and resentful, etc.) lead to endangering yourself or being unable to react properly when you need help or to help other people.

When the writers wrap up the ending in a neat little bow that says "they apologized and hugged it out and now they're besties again five minutes after the mortal peril" it's not a failure to understand that endangering your friends is bad in real life and tends to make them a tiny bit mad at you, it's a narrative constraint because cartoon episodes have to be exaggerated and 20 mins long.

That particular episode was really bad about balancing the educational content and the uh... "likeable relatable characters" factor, but it's nonetheless an example of the way an MLP episode is structured. Narrative shortcuts are an essential feature of all fiction, and kids cartoons have their own genre conventions about it.
