Warning on building=roof

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?

Thank you for the reference, but that issue pertains to cases where a highway is located behind the roof. If the warning is applied as a default for all building=roof, inexperienced users may add a layer=1 unnecessarily, which does not align with the guidelines provided in the wiki. Could the warning be implemented only when the roof intersects with an already existing highway? This would effectively draw the user's attention when it is truly needed.
