I don't want to get very offtopic, but:
Even newer embedded i586 and i686 hardware isn't cost effective
considering power consumption. When considering power it often does
not even make sense to run donated hardware ~5 years old.
I don't think this should be used to completely drop support for older
platforms but it is probably the best argument to use to convince
people to get rid of their old hardware.

This is definitely in the spirit of Gentoo, but I think the most
concrete reason to support older platforms is they are demonstrably
more secure and people may be using them for that reason.
