That makes sense. although there are other cases where the rules are different; local conservation around me is posted to keep to official trails only. > However: I'm disturbed by the knowledge that when I map highway=path, > informal=yes the majority of the rendering tools will show it as a peer to > a highway=path, official=yes.

I think you're running into the long-simmering problem of OSM where we pretend to tag reality and not for the renderer (and mostly do, the the default render is deemed to be just and example, but really it's far more important than that. And there's a legitimate tension between encoding more in the default render vs keeping it simple. > Thus, there's a rendering fix for this issue.

It would, but that's one step above deleting them, and really crosses into tagging for the renderer. I have had a related frustation, which is that in paths/footways/whatever, there is a hierachy of importance, much like the road network, and this is not entirely tied to physical attributes. I think this lines up well with informal trails, which are more or less by definition less prominent than official ones. The path/footway continues to be a problem, and to me a great part of it is the rendering difference (in normal renders) between footway (delicate) and path (much heavier). It makes sense to have the delicate red in urban areas, because typically you only want to see the footway when zoomed in. But a trail that goes even 2km through the woods is a feature worthy of being rendered at lower zoom levels. This is sort of the same issue as prominence. But cycleway and bridleway tend to be more like paths. If I were just drawing a map of many of the conservation areas near me, I'd do two things different from most OSM renders: make the official/important trails thicker than the minor ones color trails that are official and blazed with their blaze colors So I think we need a style change proposal (diff for committing, really) that has the concept of multiple visual weights for trails (paths), with mapping of a trail heavier: official=yes or a blaze color is defined lighter: official=no or no official tag and no blaze color that's a first step; there is also the case of lesser official trails.
