I think it's not very well suited for that due to their root filesystem being immutable by default. You'd need to turn that off and that's not their recommended configuration. But it's not that hard to do.
Their official way to configure the system file is creating a overlay image that contains all necessary change to root file system and load that into system. This way may be more complex for a developer to do, but is much safer to end users. Because you aren't changing anything, you only add. And fxxk up only means you need to unload the newly added image.
It'd be easier to use if it can automatically do it for you though. Something like, enter a special env, install packages, leave and it automatically pop up an image for you would be nice.
I think this is quite similar to docker image layers except it is composable
I think it's just trade off you need to make if you need to make a system that is safe for random user to use. Most linux distro (except Android) just isn't safe enough for a random user to operate at full system privilege. (And sometimes even advanced user screws up, like kernel panic during install something and unable to return to last known good status)
But this situation may change after they finished dual boot support though. At then, you could probably just boot into another linux distro for serious work instead.
