HDMI Firewall
Well, unfortunately that will never happen because the app would need a full rewrite using DirectX and WinAPI.
Fortunately there’s an open source alternative called TwinkleTray: https://github.com/xanderfrangos/twinkle-tray
Someone determined enough could add adaptive brightness to it. You can even use Lunar’s wireless ambient light sensor [1] for that as it’s simply sending lux values through Server Sent Events [2]

Apologies. I hate when people do that as well.

Connecting a Display Port 1.4 graphics card to the Dell thunderbolt dock WD22TB4
Most monitors have a Virtual Control Panel (VCP), which implements features defined in the Monitor Control Command Set (MCCS). This is a VESA standard. You can find the Input selection command in table 8-10. You send these commands over an I2C bus called Display Data Channel/Command Interface which is yet another VESA standard. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar

Opinions on functional & performance requirements for a desktop TB/USB4 AIC
The protocol is called DDC , it's a VESA standard. In there, it's called VCP features. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar note how all three mention input selection.

TIL there are apps that can control your monitor without touching the buttons on it
ddcutil (a command-line tool, and what most UI tools are based on)
-
'monitorctl' cli tool to control brightness, contrast and volume of external monitors on linux
A related non rust tool (that also has an optional GUI) is ddcutil. How does this compare to that?
- I built a widget to adjust the brightness of external monitors

Brightness issue
I've also used ddcui: https://www.ddcutil.com/#introduction, available as an AUR package: https://github.com/rockowitz/ddcutil. This has a nice GUI: https://www.ddcutil.com/screenshots/ddcui_features.png and works on everything I've tried it on out of the box.
