As long as drawing operations are the only operations in GIMP, this 
would be a reason. But there are other scenarios where a multiselection 
of layers will be useful: merging a few layers down to one without 
having to affect visibility of the other layers, copying some layers to 
another image, moving some layers into a layer group and so on. Yes it's 
a bit unrelated to your original problem. Maybe a topic for another 
thread if it's of enough interest.

It's a bit hard to understand what you mean exactly in your further 
writing. Can you write down a state chain, please?

BTW: AFAIK layer groups are still work in progress. At least layer masks 
are postponed for a later version. Filters don't work (yet) on layer 
groups, too (see bug #676768). Are there some UI specs for the handling 
of layers and layer groups? Maybe they answer all our questions and 
suggestions here. I haven't found them on gui.gimp.org, but perhaps I 
searched in the wrong place.
