The analogue here would be to create another entity to which all

Whereas this would work, it's a nasty hack just to retrieve an
extent (all instances of a particular class). Wanting a class
extent is a fairly common thing, and needing to create and manage
collections manually to help is tedious at best.
(a) It's a perfectly respectable design pattern, not a "nasty hack".
(b) The whole point is to not have to create and manage collections
manually -- you simly use the relationship.
