It's unlikely that Monday's Leopard updates signal a change in Apple's support policy since they do not address any security vulnerabilities that may exist in Leopard.

Monday's updates were the first that Apple has shipped for Leopard since November 2011, when it patched a bug in iTunes 10.5.1. The last operating system security update applicable to OS X 10.5 was delivered in June 2011.
