Yeah, I guess you're right, a single big bunny doesn't make the case for a race of big bunnies. I think flukes like that just give us an idea how big something could "potentially" get, nearing the maximum size for the species--whether that's desirable or undesirable.
I agree there just isn't enough physical evidence yet that an entire "race" of Bronze age giants existed, who were 10 to 12 feet tall. I think 6 1/2 to 7 1/2 feet could be desirable if the growth was genetic and the limbs were strong. People like that could throw spears farther, possibly run faster with longer stride (Usain Bolt a great example) and a host of other attributes. And I think evolution has seen this sort of example in the tall warriors in parts of North America, Africa, and Australia who sometimes exceeded 7 feet.
9 to 11 feet being in anyway desirable for a human frame is a hard pill to swallow as current knowledge stands, I will agree there.
