replacing apt to do it rather than making it an option within normal apt updates.

Those working on the project would perhaps better address the details of this issue, but the snappy updates are not .Deb packages, so they would not be managed by Apt. AIUI, they're file-based diffs, akin to the filesystem-level changes you would see in OS Tree or other mechanisms.

Right but note that presence of rpm-ostree with plans to enable RPM style updates on a OSTree based system.

The fact that they are not .deb updates, but are instead (roughly) filesystem snapshot diffs greatly reduces their value.

It means that you must install everything from their base image (no ability to harden/strip the system), and that anything that you install that's not part of that base image can't be maintained this way.

The idea of having two root partitions and switch between them for major updates is a good one. It is something that people should be doing a lot more than they are. But it doesn't require throwing out existing maintenance tools to accomplish.
