Indeed, "appropriate" is the key term there. I can see how to return
something that is appropriate for us, but not for general consumption.

We use rpmdeps as part of our build system (OE), and I can do some
high level processing after rpmdeps to figure out what executables are
on the path, and hence what the correct dependencies should be.

I figured that I should ask if any of this made sense in the general
case, though my initial impression was much the same as yours.
