Whats wrong with just adding objects to the visible layers?

This is pretty much what blender does anyway when you add a Cube etc. 
except it adds it to the active layer (last clicked on layer, not well 
communicated by blenders current UI) - Adding into visible layers is 
close enough.

The only case where I think giving users feedback/options about layer 
usage is where the format its self stores layer data that can be read 
into Blender.

In that case its probably best to turn on the layers that the file is 
making use of.
