I have a Hammerhead 2 and Di2. The most commonly used functionality for me was using the buttons on the brake shifter hoods to control the screens on the HH. It meant you could control the device without moving your hands and I use it all the time.

Having access to shifter position and Di2 battery levels was also super useful. This move really pisses me off!

Guess I will not be updating the firmware of my HH2 for a while at least.

yeah, exactly what I was thinking when I saw the news. I've been specing a groupset update on my current bike just last week and although the primary factor has been component availability (the only Shimano groupsets I could find were on used market), I'm really glad I went for SRAM AXS (though their wireless protocol does raise some hair as well, need to look into it a bit more when I have a chance).
