Two examples of where I find llayer useful:

- checking for results of automatic cleaning in v.in.ogr: you might to 
see the features and the cat on layer two indicating how many 
overlapping features were at the origin

- for all the v.net.* modules where by default arcs are in layer 1 and 
nodes in layer 2: I often display everything with layer=-1 and then 
display the node categories.
