Skydemon's IFR en-route charts do not distinguish those reporting points that are compulsory.  While these are not very numerous, this is  information the pilot needs to know.  Such points are shaded-in triangles or crosses on Jeppesen charts.  See for example SASKI on L179 or ALESO near Le Touquet. 

It would be good to include this information.

In principle you're right. In practice, in 20 years of flying L179/L608 both ways, I've never reported passing SASKI, never been told off for not reporting SASKI, and never heard another aircraft reporting at SASKI!  In NW Europe, I think compulsory reporting points are an anachronism.  Is your experience different?
