If you used those and can share a use case, we'd be likely to support them. +Lastly, we have some of the feature from L in +core. This should mostly work the same way in core, except for now the +core version does not create an automatic base wrapper class for your configured +components (it requires these to be catalyst components and injects them directly. +So if you make heavy use of custom base classes in L +you might need a bit of work to use the core version (although there is no reason +to stop using L since it should continue to work +fine and we'd consider issues with it to be bugs).

Its +possible if you are logging debug mode in production (please don't...) this +could add verbosity to those logs if you also happen to be calling for components +and passing pointless arguments.
