It is certainly the case that the features of that class work as
described; the bug is in the fact that there is no way (except
object rape) to get the count of the in-memory-filtered objects.
Yep, I agree. Except for the terminology used. "Missing features"
are not bugs. They are simply "Missing features."

That seems like a bug to me. Maybe that's why I still don't use
display groups. :-)
From my interpretation of the documentation on WODisplayGroup this
does not sound like a bug to me. The method
displayGroup.allObjects() contains an array of objects fetched
into the display group. There are a few methods that can change
the collection, but qualifyDisplayGroup() is not one of them. The
method qualifyDisplayGroup() does an "in-memory" filter of the
allObjects collection, so reporting from allObjects() still
contains all objects fetched. Using qualifyDisplayGroup() with a
different qualifier still needs access to the fetched collection
since it does not fetch from the data source.
If you use qualifyDataSource() instead of qualifyDisplayGroup() a
fetch does occur and allObjects() will receive a newly qualified
collection.
