It wasn't really lost. I removed it on purpose as whether the bluetooth needs to be disabled or not depends on the raspberry pi board being used by the user. As boot partition can usually easily be mounted across platforms, I just figured whoever needs it can simply modify the config.txt file either maually or can use some the hook system to modify the same.

However I don't have any issues if you want to bring it back either.

Thanks for explanation Gunjan. This is an anomaly (as most rpi/broadcom stuff) that requires all those different changes (cmdline, config.txt) instead of a single simple setting like every other board. If they're different across boards, I could make this rpi4b specific somehow. Do you know what difference the other boards would have? I've seen miniuart-something around.

I wouldn't insist on this except for the fact I'm producing images for usage in automated rigs (PXE-booting, testing labs, etc) where I need UART to work out-of-the box from the first boot, thus your remove it cos it's easy to enable after you already got in to the machine somehow else doesn't really resonate.

May be you can use conditional filtering in config.txt by adding a [pi4] section

As I said before, feel free to bring it back. Armbian also supports extensions and userpatches and customization scripts so there were plenty of ways to bring it into image as well if needed. Not just by manually updating the system. But you ofcourse already know that :)
