I think there's place for both. When I build software installers for our embedded systems, the "frontend" tools production uses are written in a "sane" language, but the actual installation of software and configuration of the systems is done in shell. Because for running a bunch of apt/tar/cp/ln/sed commands to configure a Linux machine, it is the sane language.
