I'm not quite clear what the request is - is it for a new component to enable sorting via dragging, or is it specifically in connection with creating a Kanban board? I imagine it's the former, in which case, as you mention, there have been a number of requests for this - so I'm not clear how your request is different to requests such as this one or this one. Perhaps all these requests should be merged.
As recently as last week, @George mentioned the possibiliy of developing such a component, possibly using the library you mention, so I'm optimistic. I think it would be a great feature - for Kanban boards and all sorts of other features.
That's perhaps a little unfair to jQuery and its creator. jQuery was a great solution to a problem which is now much less of a problem, so it's become less relevant.
