On the other hand, this language seems to take a subset of Python's syntax and interpret it with different semantics. I find that both theoretically neat and pragmatically smart. Making up a new syntax and writing a reliable parser is boring busywork that takes time better invested elsewhere.
Another thing to note is that the vast majority of the packages you list are things that might not be installed on a server environment; I admit I haven't thoroughly read through every single package you listed, but the vast majority of them seem to be GUI-related (Gnome, Unity, etc.) or printing related, none of which would be necessary on a server environment. The only ones that stick out as not fitting into these categories are the Ubuntu-specific things like apparmor and the various apt-related packages (which would presumably not be present on a machine that isn't Ubuntu or some other Debian-based system), clang-format (which wouldn't really necessary on a server, since ideally you'd format your code before pushing), and lsb-release (which may or may not be necessary; on the machine where I'm currently writing this, the only package I have that depends on lsb-release is mongodb, so for servers not having a database (or having a different database), this wouldn't be necessary either.
