Evidently once I've installed package A which requests X, sometimes packages
F, L, and T might subsequently get installed which also need X *and presumably
would have requested it had it not already been installed*. But when I uninstall
A it orphans X because A is the only package that *requested* it. When F, L,
and T are installed can't all the packages they *would have requested* be marked
whether or not they're already installed? That way a package would be orphaned
only when the last package that needs it is uninstalled? Or am I missing
something?
