Currently the overall code to instantiate Cache drivers cannot be generic.
This can be noticed when you compare APCCache and MemcacheCache drivers.
The first one is simply a no argument instantiation. The second, even after isntantiation, it still requires you to call a method (->setMemcache) in order to work.
This is not optimal for generic approaches, creating unreliable conditional situations. Also it is not extendable, allowing user to build his own driver.
A suggested approach could be a CacheManager as a fatory.
Another one would be Cache interface assigning a contract to receive an array of options.
Anyway, this should be fixed VERY soon.
