I ran across a question today with the following close reason:
Questions should demonstrate reasonable business informationtechnology management practices. Questions that relate to unsupportedhardware or software platforms or unmaintained environments may not besuitable for Server Fault
With the particular question I was looking at, I think it was more about "reasonable" practices (and I will try to keep my opinions to myself on that point), but it got me thinking: What is the rational for not allowing questions about unsupported platforms? It's been my experience that a big part of being an IT professional is dealing with old stuff. ServerFault has helped me a time or two when some content locked behind a sevice contract seemingly vanished from the internet. Additionally, it seems like this policy would be a problem for existing questions whenever a platform reaches end-of-life or a company goes out of business.
