I have seen no issues so far mixing drivers w/ and w/o Giant. But that won't be true once drivers stop inheriting Giant when entered "from the top". It's not clear to me that it's any more work to lock drivers than to provide some sort of compatibility shims. Regardless this won't be an issue for a while. Mind you I am still tracking at least one nasty bug... Sam
