but the experience through the plugin is different than what designers are accustomed to if they imported a UI kit that was created/exported/shared through XD

Note that plugins currently can’t create new Components that appear in the Assets panel – please upvote Create Symbol if you need that. But you can import content as a plain Group onto the artboard (e.g. to create a sticker sheet), and you can add colors & text styles to the Assets panel.
