Pocket screwing is a great way to solidify projects. My only concern, but I'm certainly not speaking out of experience: In Southern regions where folks have small hive beetles, I would worry about this giving the beetles a place to hide. You're further North than me, so no worries for you, either, but I wanted to point this out as a potential issue for those further South.
I use rabbets, glue, finish nails from a gun.
