Sorry, just getting back to this

It's not a function of the slot, it's a function of the item category being flagged as a weapon. It functions as an instrument, has ammo like a fishing rod, loses TP like a weapon, and is the smallest item category in the game.
Sorry, but you are flat wrong. I even went and bought a 1k horn to go check on my lvl 25 BRD.

Naked with just the horn, i ruffed up some rabbits in east ron. Took off horn and poof went the TP. Did it a few times and its not a fluke. Then to be thorough, i ran back to MH and swapped to SAM for meditate and grabbed my fishing pole. Ran that test outside MH, same result-TP was lost.

Now i didn't test TP loss from switching out the Ammo slot. There is no need there because i know from first hand experience on RNG and THF that you can swap ammo until the cows come home and never lose TP. As long as swapping ammo doesn't force a de-equiping of whats in the /ra slot of course(ex- You can swap all arrows with each other w/o losing TP. But suddenly swapping in bullets would cause a bow to de-equip, and all accumulated TP to be lost.)

So there you have it, you learned something today. And oddly enough, i still think your idea is kinda cool.
