Why can't windows and macos adjust monitor brightness natively via dDC?
Why do they not allow doing the same for external monitors using DDC? There are several apps that do just that.

Making the "xrandr --setmonitor" setting permanent
If I were you, I would take a look at ddccontrol. It's a utility that allows you to query the state and send commands to your monitor via the command line. I currently use it to increase / decrease the brightness of my monitor depending on the time of day.

Automatic Desktop Monitor Brightness Adjustment
Before I look into automating it, I wanted to get it working first. For this, I have a tool called ddccontrol (https://github.com/ddccontrol/ddccontrol). But this needs root privileges. So I'm just wondering if there are other ways, since I couldn't find any.

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.

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.
