For your second point, you can never really know what other work depends on your package. You could display a message in the new package or in the readme for example, but that's likely not going to work well for various reasons. (but see my last comment)
However, what Jay is saying I believe (correct me if I'm wrong), is that you can just create a tag for the previous version, modify your current package 'my-package' on the pkg server to refer to that tag, and create a new package 'my-package2' on the pkg server pointing to master. The pkg catalog is going to be cluttered with all backward-incompatible version numbers but a) Jay doesn't seem to be worried about that b) it's currently not the case (meaning, people don't do that currently, but maybe they should?). Old users won't see the breaking change, and new users will see and use the new version on the catalog (or clone directly from github). What's missing again is a way to tell old users that a new package is available with new features, but I think Jay was saying some time ago that this should be the purpose of mailing lists and other media.
