Partially because I'm currently in the process of reworking Kalpa to use the Tik installer, rather than YaST, as part of progressing Kalpa to a beta release state. Fixing issues in the YaST based installer is low priority at this point. Additionally, Kalpa doesn't install `Recommends:` by default, which is part of how we keep the base install image so slender. That's the mechanism through which Leap/Tumbleweed/Slowroll ensure that `-lang` packages get installed. And at least at present, there's no way to tell zypper "Install all of the list of $X packages --no-recommends, but make sure that you install the -lang packages that are listed as Recommends:"
