I'm not sure which way I lean, but I suppose there are two camps/use cases here: 1) People who regularly use one or a couple of package managers who can update all packages with a few commands. 2) People who regularly use packages from a variety of many different package managers, for whom running `update` for each one would be more cumbersome than just running updates on the packages themselves. I don't know which way I lean, but I don't see the harm in having a self-update in the package so long as you can also update via gem, but maybe I'm way off-base.
