I've noticed a similar concern when I have an application team
"re-tool" for a new target and the prefix change results in a
discussion about why is this changing.  It doesn't happen often
enough, but their is always an extra prefix variable in any
application developers configuration they maintain for the particular
target they use. I'd agree the generically named folder structure
would cleanup use and documentation from a SDK users perspective.
