It very well could be, I do not know. I am sure there is an RFC out there that recommends it SHOULD be treated as lower case... I don't think it is much of a performance hit in my environment so I turn it on to be safe. I use it a lot when I am working on URI's as well.
Almost certainly a good idea! I just happened to run into it once when I was entering capital letters in my browser and had my iRule looking for them...turns out the rule never saw the capital letter because the browser (or something else) was lowering them before it got to me.
