I agree, a package sounds much more like an "archive" than what is essential (from a new users perspective) an installer. On the other hand package is established with more knowlegable users as is (to a lesser extent) archive so unless we can think of a name which is actually unambiguously better wouldn't looking at the workflow for common uses of archives be better (e.g. offering to "combine" files on upload or similar).
