-1 to this being default behaviour.
IObjectModifiedEvent is fired from EditForms, not from forms in general.
Normally, an EditForm is used to edit "a context". The groups could come
from various locations (we use groups to create fieldsets based on
schema hints, but they're all logically part of the same content
object). I would not expect more than one event sent (in fact, doing
this would significantly break code in the wild).

I think you should override the action handler and do this for your
project. I don't think it should be the default behaviour.
