I'm not sure what is the best behaviour.
I tend to think such options should be simple to understand
with only 3 cases:
- no option -> default
- enable option -> only core mandatory and listed libraries
- disable option -> all but the listed libraries
It looks simpler to forbid having both enable and disable libraries.

Would you be open to change the behaviour of the drivers options?
