I think that per-group "switch" is not nice as well but if we make it
hierarchy specific (which I am proposing for quite some time) and do not
let enable accounting for a group with tasks then we get both
flexibility and reasonable semantic. A global switch sounds too coars to
me and it really not necessary.

Would this work with you?
