<PRE>For some callbacks you may need to check but only if you need to perform
a different operation when it does/doesn't. For example if you write to
files a PUT is the same operation either way, but if you write to an SQL
DB you will want to do INSERT/UPDATE depending on that. Same goes for
is_conflict and others, it depends.
So sometimes you need to keep that info around in the state and
sometimes you don't.
