As a developer I can tell you that may come back to bite you later, especially if you're dealing with system timings or drivers. You are safer if they're only writing high-level stuff, but there's still no guarantee.
I didn't mean it in that way, though our developers aren't really writing device drivers or other low-level stuff like that. I just don't want them to have overly optimistic expectations of what we can deploy to our new hardware. You know how it is with them delvelopers. They'll eat all the resources you can throw at them. :-)
