Comment (by harrim4n):

 Until (if) this is implemented, I suggest adding a check when .get(),
 .filter() etc. are called on such a QS. Currently the error messages (if
 there are any) do not explain the issue, the only way to find out about
 this is in the documentation of the QS API, section union().

 Example:
 {{{
 qs1 = User.objects.all()
 qs2 = User.objects.filter(username="nonexistant")
 qs3 = qs1.difference(qs2)
 print(qs1)
 print(qs2)
 print(qs3)
 print(qs1.get(id=1))
 print(qs3.get(id=1))
 }}}

 This fails with (could be any number instead of 4, of course)
 {{{
 MultipleObjectsReturned: get() returned more than one User -- it returned
 4!
 }}}

 Even worse, if the difference of qs1 and qs2 only contains one element,
 this element is returned when calling qs3.get(id=1) without any error
 message, even though the objects ID is not 1.

 I'd like to see it, but it will be a much much more invasive change and is
 not something I will have the time nor motivation for in the near future.
