well, on Linux it is only half of RAM by default, and configurable. And not sure what is wrong with that either. After all, Linux without ZFS also fills whole free RAM with cached data.
Perhaps you are misled by output of "free" - ZFS caches count as "used", while other caches count, more logically, as "buff/cache".
Devil could be in details - if you have much more non-ZFS data than ZFS data, you probably don't want to give ZFS cache half of your RAM. And I am not sure how nicely ZFS plays when kernel needs to evict something.
