CEC support was added in to the Dock in May 2024 https://store.steampowered.com/news/app/1675200?emclan=10358...

Bluetooth wake made available for LCD Decks in September 2025 (it was already available in OLED models) https://store.steampowered.com/news/app/1675200/view/4983336...

I will say that the Deck has less than stellar bluetooth reception in my experience too. I settled on an 8bitdo controller because my XBox Elite couldn't stay connected from across the room. The Steam Machine has a dedicated antenna for Steam Controllers though.
