What's the downside of the coupling plus bushing?

I'm thinking that it's two joints to go bad, instead of
just one.

Yeah, that's true. But properly done, the probability of a
PVC joint leaking is extremely low. I can't think of a single
one I've done that has leaked. The alternative, wasting
God knows how much time looking for a fitting that
avoids one more joint doesn't seem very appealing.
