I wonder if a big part of this is that you are against a wall at the time. The game designers probably want having your back to the wall to be dangerous. They don’t want it to be like neutral, and combining that with all the mechanics happens to lead to throw loops. They don’t want to adjust that because it might make the wall less dangerous.

One thing I’ve heard people say as a rebuttal is that if throw loops are an important mechanic/strategy, why can’t all characters do it? So in my mind that supports that idea that it was a result of making the corner dangerous, and I’m not sure there’s an easy fix for that.
