I agree with Gary about a truly minimal core (though I'm going to stay out of the naming argument, it's one of the two hardest problems in CS). My largest use-case doesn't involve parsing any sort of configuration -- it's all programmatic. I'd benefit from the ability to run without any sort of DI, plugin system, or configuration parser.
