Persona / analytics based content loading/unloading
Aka: 'User journey' context based caching... deterministic?
C::Logging -> C::BuildDeploy -> C::DOM
Assuming PageDriver will have an eventual stats/analytics digest - it would be cool to create (perhaps dynamically) a set of top product usage workflows - then as users use the product identify which workflow correlates closest and and preload any required content before they need it as they go down a certain route.
Re: potential use of https://developer.mozilla.org/en-US/docs/Web/HTML/Preloading_content ... if adding tags programmatically after page loads does not function, and there's no JS method... maybe generating a dynamic iframe document that does could work... lol.
Only gotcha is increased bandwidth and processing consumption if a user is actually carving their own path - but hey, not everyone is a special snowflake :p
