It's probably safe to uninstall the acs-api-browser and acs-core-docs
packages (haven't tried it myself though). However, why would you
want to do that? If you don't want people to be able to access them,
just use the Site Map UI to change the permissions on the packages.
For any package that is not installed, deleting all its files from the
filesystem is just fine. E.g., "rm -rf
/web/mysite/packages/my-unused-package".
