import on demand support?

[maicWorkGithub]

I checked document, cannot find import on demand, but only fully import

[Mt-Youya]

This is Canvas Element , all shapes are Canvas drawed , v-stage is canvas wrapper div dom , v-layer is canvas dom element , v-image is Canvas context drawed, v-circle is Canvas context drawed , v-line is Canvas context drawed... , all shapes are not dom element.
So, I think Canvas can not support import on demand
