Ristretto boiler pipe

I recently came across these aftermarket boiler pipes for the 9Barista, specifically for making ristretto:

The idea is very simple, the boiler is filled with 120ml of water like normal but the shorter pipe means that only 20ml charge can make it up the pipe instead of 40ml. This avoids the need to do the "ristretto hack" of under-filling, and instead just screw or unscrew the bottom section of pipe.

Has anyone used this product or knows if it works with a Mk.2? I'm also tempted to just order a spare Mk.2 boiler pipe and shorten it myself since the OEM part is significantly cheaper. Then just swap the entire pipe over as needed.
