Inactivity, sure. But you don't need 12 years of that to trash an engine 
There is no obvious engineering reason for the 12 year life limit on an engine that is running regularly.
Hoses are a separate issue. They are all external and yes they can and usually are lifed. But again there you can have Teflon hoses which have no inherent degradation mechanisms. On my plane (TB20) Teflon hoses are not lifed.
