Is there something seriously wrong with zypper/pkcon?

Maybe it's only me (I'm used to Archlinux's pacman), but I expect this behavior:
When installing a package, it should install all the dependencies, if available.
When removing a package, it should check whether the dependencies originally installed are now owned (required) by any other package. If not, it should remove them, or at least notify the user which dependencies are no longer needed by any installed package so the user can remove them.
