It would be cool, but I cannot imagine it being at all fast. But maybe
with some kind of delay timer that strokes the path on a temp layer after
the user hasn't moved the node for a little while... It could be done.

That would a pretty simple interaction change in our old path code
(which we still need to port...) If we would extend KoPathShape
with stroking using Krita brushes instead the path would always be
"live", but you wouldn't be able to stroke, change the path and then stroke
