Why don't we allow questions about unofficial remixes/derivatives/flavors of Ubuntu that are still using the official repositories (e.g. they have nothing in sources.list besides archive.ubuntu.com/*, etc.)?

I'm not talking about something like Linux Mint, that's an entirely separate distro. I'm talking about something like the Ubuntu GNOME Remix (the original, before it became an official derivative). It seems to me that these systems are not different on a technical level, except which packages are installed by default.

If I can exactly create a setup provided by a remix, just by installing and removing packages after a regular Ubuntu install, that would be suppored, but if I installed via the remix install media, it isn't. What's the difference?
