I would be against it.

We are an official support site so it would be logical to no support end of life releases. It should be the official stance to upgrade to a supported site if not just for security related problems that can arise. Besides that: if the release is important most of us will not be able to check our answer (since none of us will not that have that release active).

I might be wrong but questions about end of life releases can still be asked on http://unix.stackexchange.com/ So there is a place to ask questions; just not askubuntu.com
