If foo.spkg is *uninstallable* without another package bar.spkg being installed, chances are that foo.spkg somehow *links* against something provided by bar.spkg. If it didn't link against it, I bet foo.spkg would be installable without bar.spkg being installed. In any case, I'm the one whose butt is on the line, since I'm the one responsible for hosting these packages.
