Opinion: regardless of how many people express an interest right now, this is something that needs to be done. Reasoning: these are numbers you are not likely to examine unless you are in pain. If you are in pain, you are suddenly placed in a situation where being without metrics puts you in the uncomfortable position of guessing in the dark. And you don't get in this sort of position if you are working on a desktop OS, you get into this position when you start to really use the OS as a heavy server system. FreeBSD's stats are not BAD but they could be made more useful... what is useful? I think that that is one of the things that needs to be quantified. Transfers per second and average time to service transaction seem to be two obvious things you would want to know about your disks. :-) ...
