I'm not worried about reentrancy (exactly) because if you ended up being
reentrant, you did it to yourself (i.e. it'd be pretty insane to call deliver
inside of a delivery callback. However, if you didn't want your callback
invoked, then you have to jump through some hoops to save the records away
somewhere. Basically, this might lead to some awkward code patterns.

So, yeah, let's go with something that simply returns the records directly and
doesn't invoke the callback.
