What does a package manager "using" SemVer for apps look like in any meaningful way? The package manager never has to do any dependency resolution against the version number of an app, so, I would assume (and know, for the package managers I'm familiar with), the version number is just an arbitrary sequence of three numbers. A version number only becomes semantically relevant the machine when other things depend on (aka, use the public API of) it.
