It does not. Source: have a dock. Latest firmware installed from deck. And because the current Steam controller is a recent release, I had to try a whole mess of third party controllers before settling on PS5 controllers because everything else I tried had Bluetooth pairing issues / disconnects as you approached four controllers. SteamDeck as a handheld is great plus or minus a few nits baked onto the power / battery life choices Valve made. SteamDeck -> TV and SteamDeck -> USB-C KVM are both workable, with caveats. I had hoped we would see the bug fixes you describe before the Steam Machine release. Alas, no.

You are confidently incorrect. SteamDeck supports HDMI-CEC as of 3.7 ~2 years ago, using the original dock or select third party docks. --- How to Enable CEC: Press the STEAM button and go to Settings. Navigate to the Display tab. On the right side of the screen, find and toggle on Enable HDMI CEC Support. Ensure Wake TV when device resumes from sleep is also enabled.

CEC support was added in to the Dock in May 2024 https://store.steampowered.com/news/app/1675200?emclan=103582791470414830&emgid=4213757668851885208 https://store.steampowered.com/news/app/1675200?emclan=10358...

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.

  It's a Bluetooth problem in general. If you have 2 or more controllers, you're often better off going with wifi dongles.

Read the other replies, and i’ll restate that you are indeed confidently incorrect: i have been using this feature since the update that added it. i use the steam controller and i am using the original valve dock.
