Hello Dirk,

this is what I do when I map a bridge or find a bridge where none of the
crossing ways has a layer tag.

I tried this once. After having added layer=-1 to the stream the it was
partially no longer visible on the rendered map.
Probably there were additional problems like the river not sharing the
nodes of the forest or overlapping forest polygon and waterway but I did
not want to fix/change the whole stream and/or forest because I simply
added a street crossing the stream.

I think it would be better for the quality of the data if the validator
encourages to add a bridge tag and think about the relative layers at
this place than adding a general layer=-1 which may hide warnings about
missing bridges.
