Many people here seem to think this change will allow for people to package their Linux apps to be portable across distros/distro releases. If this is true then this a great!
On Debian-based distros it kind of sucks when the version of a package is only available in a newer release so the only way to get it is either compile it yourself or upgrade your system.
I remember trying to hack around this once by downloading dependencies from a newer release and helping the program locate them but I think I ran into a issue with the linker version being hardcoded or something and gave up.
