Its an internal library¹ used to share code between apt, apt-get and co which is too specific to be moved into the real shared library libapt-pkg (or its ugly cousin libapt-inst), but creating "fat" binaries isn't in our best interest either. The mentioned symbols (which are implemented by the respective binary itself by the way) are the best examples for this: The --help text and which commands (like install/remove/clean) a given binary supports (and which function is used to deal with it) are of no concern for other apt-frontends and so do not need to clutter the ABI/API of libapt-pkg and even in libapt-private it makes no sense to define them as its different for all of them, but then I am lazy and don't want to maintain pretty much the same copycat calling code in each frontend… I guess to appease adequate I can pull some weak symbol magic, which I initially intended anyhow, but part forgot and part found useful while working on this change. ¹ if "-private" wasn't enough of a hint, headers aren't available, no symbols/shlibs file and exactly nobody cares about ABI/API in there.
