Well that should be possible too. However if you add a package later, it would be easier to edit your own package file then to log back in to updateditis and re-upload a package file. Automatic for the people

yes, but IMO it should be provided as a feature, not as a requirement. I'm probably in the minority here, but I prefer general solutions to 'github extensions', as when you host projects elswhere all those useful tools become simply worthless. especially that using a package manager and using github isn't necessarily tied together.
