Problably more in unspecified territory than really intended/designed. 
-al and giving a layer name should probably be mutually exclusive. Not 
clear if at that point of history it would be worth changing that to 
error out and breaking existing user workflows...

-json is a bit specific in the way that you mostly use to feed other 
code and so you don't necessarily need to have as many different level 
of details as for for the text / human friendly output.

It would probably wouldn't hurt mentioning in the documentation that if 
both -al and layer name(s) are specified, the later will override the 
former (but that users shouldn't rely on that, in case we change our 
mind at some later point)
