It may not be possible with the current nano state.

First of all resumability requires the library to be able to fetch modules on demand which requires a special compilation to generate such modules. Qwik does such loading by propagating events to special handler which is able to determine which module to load. Those modules has to be separated into two pieces: logic and UI. UI shouldn't replace old nodes with identical ones to conduct true resumability. But as far as I know nano even in current state with implemented hydration just generates and replaces a non-interactive DOM tree with the same but interactive DOM tree. The hydrate function is just an alias to the render.
