While I agree with this, by and large, there can be good reasons not to
follow this rule when we disagree with the issuers.

This a good example: I think SGI made a pretty good effort of supporting
IRIX for as long as it could make sense, so I'm fine with dropping IRIX
support at the same time as SGI.

Note that the issue is not really software support but hardware support:
Apple is pretty aggressive about dropping support for old hardware in
its newer OSes.  They could make OSX 10.11 work on my old macmini but
decided it would be counterproductive for their business.
