Previously, there was a 2-step initialization, where you'd create the object and then
set it's backing. But this means there's an intermediate state where the object exists
but has no backing. Better to just use a 1-step initialization where the backing is
passed into the constructor, which eliminates that extra state, thereby simplifying
the class.
