Is that clear? It's not as if when SGIs are taken away, developers efforts will seamlessly efficiently shift to amd64. I like to think that "oddities" like SGI are data-points to test against, and help keep abstraction alive by disallowing traps like pretending that everything is an x86.
I'd be interested to hear whether or not this is the case from people closer to such a condition, though (ie: OpenBSD, NetBSD, ???).
If they would rather refuse free hosting and will "not allow the conversation to that way" then it means they want to keep support for some physical hardware that's hard to find in existing datacenters.
This is like saying "I don't care if my arcade goes out of business, I'm going to keep the power hungry cabinets alive even though they only get used once every 3 years."
