The attack that hit my packages two weeks ago was a patch release, taking advantage of this exact assumption. Wasn't a Post-Install script either.

With all of the latest in automated scanning and whatnot, this is more or less a moot point. You'll know when a package is vulnerable, and the alarm bells are loud and unambiguous. I really agree, and have always pushed the point, that version ranges are the worst things you can have if you care about supply chain attacks.
