I don't think this is generally true. If you are running Linux in your stack, your device probably is investing in 1GiB+ RAM and 2GiB+ of flash storage. systemd et al are not a problem at that point. Running a UI will end up being considerably more costly.

I can assure you there are many Linux devices with specs significantly lower than that.

Sure, but devices that do that are not running a Linux distro off the shelf. They are creating something custom with the minimal amount of dependencies possible.
