Many of the caching plugins didn’t start out as complicated as they are today. This looks like a great plugin — I’d hate for it to lose it’s way and become a total caching ( ;) ) plugin. KISS!

It is inevitable that it will become complicated. Invariably you'll end up serving stale content and people will complain and you'll have to add an exception for that particular use-case. Then that will break something else and you have to fix that and so on.

Besides it's no fun caching stuff for an hour. Most sites don't get enough traffic for that to save any server resources. You have to cache for days. That's where you get into trouble with nonces expiring and what not.
