How to reproduce the issue?

When creating a building=roof, iD is raising a warning if a layer=1 is not entered, even if the roof is not intersecting any other feature.
Anyway in the wiki is clear that layer=1 should be used when 2 or more features overlap, to express vertical positioning. Also the wiki page for roof is describing the use of the key layer only when roof is overlapping with something else: https://wiki.openstreetmap.org/wiki/Tag:building%3Droof
So, why this requirement and warning on iD?
