[Tagging] Road hierarchy

Road hierarchy is needed for a number of things:
* deciding which classes of roads to display on different scales in a map
* performing road network validation
* other tasks (f.e. typification of buildings - orientation)
Hierarchy would be different in different context: motorcar, bicycle,
pedestrian etc. For the time being I'm only asking about motorcars.
There is non written (or I could not find in wiki) or "de facto"
In some regions unclassified has a higher position in hierarchy, in other
regions unclassified, residential and living_street have the same position.
This is fine for the time being.
I'm also intentionally skipping _link classes.
My question is about what goes further:
track / service
Which of them is higher?
Does additional tags influence this? For example does adding
service=driveway reduce position in hierarchy of service road? Does any
value of tracktype change position of track road?
And in general, is there a point of agreeing on this globally or it will
stay regional anyway?
