Glad you are enjoying it and that it's living up to the hype I thought it would have! Your reactions are priceless though, that's exactly how I felt when I started to get into modding my keyboard, how insane the responsiveness is, how everything you do happens exactly when you tell it to. It truly is an amazing feeling when you realize you are held back by out-dated hardware and can finally realize your potential.
This is basically the performance you can get when heavily modding keyboards. I would probably play without the key-caps though, at least for space and arrow keys, then you can get more control over the pressure you apply and can utilize the rapid trigger better. That's how I rope anyway lol. I tap on the triggers, not the keycaps. You have massive hands though, my hands are tiny compared to yours so this might be a little advantage I have to play like that.

This rapid fire mechanic is actually another layer to your skill as a roper, if you become better at applying your force when tapping you can get out faster and more rapid presses, that's a skill in itself since you don't need to press the key down all the way any-more. People that learn to tap more delicate will have a distinct advantage there.
Now everyone can get the joy out of super responsive keys without any knowledge of how to mod keyboards, pretty expensive and I wish it was here back in the golden ages of warmers with lots of people to play with, but I totally plan to get one of these in the future, this will change gaming as a whole, not just Worms. You want these features in most games, highly customizable keypresses are desirable in all games really. More manufacturers will appear and prices will probably go down a decent chunk.
