I'm going to look into adding this in, thanks for the tip!

Most likely the update will contain the boot.img which would overwrite you're rooted kernel, assuming a rooted Samsung device still takes updates.
The carrier can look at the packets TTL and assume if it's not what they expect then it must have originated from another device via the hotspot. Verizon did, or maybe still does, use this to throttle hotspot traffic but not data originating from the phone.
Bambu labs recently updated their printer firmware to support this feature, but it's nothing new. If you have a printer that is running or can run klipper, you can enable this. The final piece is a slicer that labels objects in the gcode so they can be excluded. I know both Prusa Slicer and Orca Slicer provide this functionally, there may be others.
You can add the Kingroon KPS3 Pro to the list of printers you might consider.
You can have any color you want so long as it's black ๐
I think what's happening is the app is using Android's account manager to store credentials. These are part of the system and not removed when an app is uninstalled.
If this is what's happening then you can go to "Passwords & accounts" in settings and find the account to remove. There really shouldn't be any data left over and you shouldn't need to clear app data and cache before uninstalling, the system takes good care of that when the app is uninstalled.
So I add that as an include from another config. It's saved me from a few complete failures ๐. For this I was trying to keep it as a basic config for others to use as a good base and I would like to submit a PR, eventually, to include it in klipper's example configs.
