@stof could it be expected that the DoctrineBundle someday drops those commands in favor of using DoctrineCacheBundle for this? maybe DoctrineBundle could even not register those cache commands anymore when DoctrineCacheBundle is present, if those are redundant.

using doctrine-cache to separate from doctrine:cache does not sound like a good idea to me. its even more confusing. as long as we don't have clashes i could live with a mixed namespace.
