Hi Erik,
What is important is that it's possible to distinguish the edited version from the original one. As of now, users cannot tell which variant of the package they've installed.
Why is this important? I believe there is no difference between two revisions after they're installed, at least not currently, since you're only allowed to edit dependency version ranges [...].
suppose my application foo-1.0 depends on bar >= 1.0, but it turns out that bar-1.0 has a bug that's fixed in version 1.0.1. So I edit foo-1.0 to depend on bar > 1.0 instead. Now, a user of foo-1.0 sends me an e-mail and complains about crashes in my code. At that point, I cannot know whether he's using bar >= 1.0 or bar > 1.0, because the version number of foo didn't change after the edit. Best regards, Peter
