The short answer is: if you want nesting, use the object that allows for
it: a sub form.
Sub forms are just like regular forms, except for the class name, the
default decorators, and one or two items of metadata. I have no idea
what you mean by "you have to set decorators for their elements
individually"; you can call setElementDecorators() just as easily on a
sub form as on a regular form.
Display groups are intended simply for grouping *elements* in a form --
not sub forms or other groups. The grouping is for cosmetic purposes
only -- hence the term 'display'. The elements in them actually belong
to the parent form, so having them namespaced differently is outside
their scope -- but well within the scope of sub forms (which are
intended for this kind of logical grouping).
