Moddable Piu vs LVGL(JS)

[matthewruzzi]

From what I have seen, it looks like Piu is a lower level framework than LVGL(JS). LVGL(JS) has many prebuilt widgets that I don't see in Piu. Is this correct? Would it be possible to make Piu more like LVGLJS or to port LVGLJS to run on Moddable XS?

GRVL is another UI library that looks interesting if it could be integrated with Moddable.

Slint is another UI library with JavaScript bindings but it currently only supports Node.js and Deno. Would it be possible to integrate it with Moddable?
