I totally agree, at least on the desktop. My /usr isn't required for any of my customers' projects to run, and it probably shouldn't be - I have environments and VMs and containers for all that stuff. But this is an SBC. It's likely to be configured to run its specific task forever. It should automatically log into the default user's account, and automatically start whatever software you want it to run. Software for it is likely to come from cross-compilers and to be sent over SSH. It doesn't have hundreds of gigabytes of high-speed storage, the entire OS needs to be copied from a microSD card on every boot, so you don't want to have multiple toolchains on it. I really like the DietPi [1] environment for these purposes (though it doesn't currently support have the Jetson Nano), the setup scripts make it easy to configure the OS for exactly the tools you want.
