Subaru is basically telling you "If this wears out before 36K and you weren't abusing it, it wore out too fast."
But what you descrine would be abuse. Could be considered fraud if you claimed they "just wore out" even - they can see if the clutch has gotten hot, and if your rotors are glazed/warped etc. they could see you've been racing it, know you were lying, and wouldn't replace your brake pads.
So, if it just wears out on its own, yes, you could try to get it replaced under warranty, but it would be a really bad idea to wear it out on purpose and then lie to the dealer, because there's no guarantee any individual dealer wouldn't try to screw you anyway and/or could not tell you had intentionally abused/wore them prematurely.
Sounds like RainRacer's car had clutch problems from the get-go that caused it to wear out (weak springs) and they replaced it. That's cool. My 350Z could eat a clutch in 15K miles, not even being abusive, but Nissan's warranty was for 12K. See, they make that warranty knowing full well that clutch/brake pads aren't likely to wear out before 36K (or whatever the particular mfgr warranty is) miles unless you're abusing them. Or, in the case of the 350Z, it's too wimpy of a clutch to handle the power.
