That makes a lot of sense. Here is the spring, btw, which I was able to find with the help of this distinction: https://www.thelumberyard.com/SPRING-EXTENSION-BLACK-32IN-p/5658042.htm

So basically whereas a torsion spring is always already under tension, and thus has a ton of potential energy stored up, an extension spring is not under tension until it is extended (like a trampoline), is that right?

Yup. These kind don't have tension on them unless they are extended. So all the way up there's usually a slack spot.

TBH when i removed mine i barely had to pull on it to unhook the S-hook. All the way open and the spring was pretty much fully closed and had next to no tension. I just wore gloves so i wouldn't pinch my hand. These are waaaaay different than torsion springs.
