I typically do not use dominos in face frames as they are well contained once mounted to the frames.
The last face frame (oak) construction I did (for own use) before I bought myself a Domino, I used an invisible nailing kit (nails countersunk under a raised shaving of wood). And, while I didn't use any type of attachment between rails and stiles, it's held up well. But in saying that, I've always been apprenhensive about the wood suffering expansion and contraction problems producing gaps.
Now, I'd want to use the Domino to attach the rails and stiles if only to add a little extra support protection against possible gaps appearing.
