In my perspective, FreeNAS is A product, which provides graphs. Many users dont know which software provides, and even dont care.
From this point I would fix the graphs. Even with that the current graphs are pretty useless.

They dont, but we developers rely on these softwares.
We are not experts on each and every software used in the product and bringing arbitrary patches skipping the release process of a given third-party software may affect us in a bad way. In general, its better to be safe than sorry.

Several users (including me) are seeing an odd or even erroneous ARC Hit Ratio reporting behavior. I'm not sure if this behavior was introduced with 11.1-RELEASE or 11.1-U1. It is just my guess that this behavior is a consequence of the changes made during processing bug #25966.
