I am not sure, because I can not judge the effort - I think info should be available, because Kurviger has sent routing request to server - so in that case it just has to be put into a link.
In many trouble cases it is much easier and faster to analyze, if a shortlink is provided.
And sometimes it its really difficult / nearly impossible to find the issue without a shortlink which gives you the possibility to have exactly the same route, example:
Remark: Also exporting a .kurviger file to give an exact, precise route is not possible.
