The problem is that this would create duplicates if an older item got an
update. E.g. what if the oldest item (in currently parsed feed) is a year old
item that was updated with new content? Since the updated item wouldn't be
checked against your local copy, RSSyl would consider it a brand new item.
This is why such setting would need to be off by default (check everything).

I will look into the caching idea, as that seems a more systematic approach to
the problem. :)
