There is a very important reason for Lua: it's the only way to do
scripts without requiring an external interpreter. For packages that
are part of the minimal rootfs required for building packages or
creating containers or whatnot, this is critical in order to prevent a
circular dependency error (package requires /bin/bash but bash isn't
installed and can't be installed until the package is installed
first). So, we do need it.

Also, why can't the work you're doing go into RPM itself? It would be
pretty nice if more of RPM's capabilities can operate in an
unprivileged state.
