Follows-up I30263f552efe. No need to reflect internal detail of it being in uppercase (which might change). Use the canonical casing instead of improved reability. Also removes the illusion that this might be special (which uppercase strings might make you think). Change-Id: I7cecfdf5991e85c85862465a27a86af7bc8c0763
