Sure, I'll let you keep the roll, I've no problems with that.
Basically, walking around with your weapon ready, but it seeming like it's not ready, is having your cake and eating it too I feel. Just because you can hold an item doesn't mean it's readied. Or to put it another way: you can walk around in a town using your halberd as a walking staff, and you'll get the occasional funny look, but you'll be left alone. If you walk around with it readied, people will give you concerned looks and probably go complain to the law that there's a 'troublemaker' in town. Also, I feel that carrying a weapon around perpetually readied would devalue feats/abilities like Quick Draw and Knife Basics.
