Yes, this was the original plan, unfortunately to containerize the app was too much work to make it in time for release. This will also make it easy to install the web app on any other system so the standard units can have a nice UI as well.
I would highly suggest against this.
'Containerized' apps require the producer of the container to regularly update the container whenever a problem is found with any software included in the container, and thus also require each person running the container to update their container when this happens.
The long term result of this is: most people running old, out of date software in their container, usually with various known security issues.
If instead the OS (like ubuntu) is allowed to update the 'system', this solves that issue for hardware that no one bothers to check.
The basic issue is that this device is expected to be directly connected to the internet, so a design leading to commonly unpatched security issues is problematic.
