It would be nice if you didn't force the execution of a phase

I like to execute this plugin standalone and we also sometimes employ a custom maven lifecycle for some of our builds.  I would prefer it if when I executed push or update on this plugin it didn't assume I wanted to also execute "package" on the default lifecycle.

If always executing "package" is a must for these goals then another option is to provide alternative goals that don't execute "package".  I could submit a PR that does that instead if requested.
