When I use to fiddle around with it, it was very interesting to me, it was kind of like playing chess with your body parts. But after time, I lost interest.
Well, you are better than me because I never fiddled around with it, at least not the hidden pressure point stuff. As a practitioner of Hapkido, when I practice poomsae, applications do jump out at me, and some of my instructors have given examples of self defense movements contained in forms. But I do not practice poomsae for self defense purposes, so I am not really into all of the explanations of the applications. I have Hapkido for that, applications which we practice directly, against a live resisting partner, rather than solo, fighting an imaginary opponent. But if other people wish to delve into the hidden form applications, triple warmers and all of that, they more power to them.
