From my side I had no need to discuss, I really like this idea.

I mean, I really like this suggestion.
Only problem is the FindCONFIG.cmake and FindMODULE.cmake case...

If we can find a way how to avoid this problem I'd be all for this solution.
Enabling the keywords MODULE and CONFIG only via a policy ?
It could warn if the name of the package is one of the known keywords or looks 
like a version number.
Not that nice, but maybe acceptable for those uncommon package names ?

Or make the keyword more unique, i.e. longer ?
find_package(CONFIG_MODE|MODULE_MODE Foo)

Doesn't look that nice, but should be safe enough.

Other ideas ?
