Not sure how consequential it'd be in practice, but my first thought is that "+vl" and "+vL" (or "+v"/"+V") would require fewer logic changes and extra checks for parsers. Plus, establishing a v-prefixed convention for views would avoid those downsides for plain binary types when BinaryView and Utf8View are added (e.g. "vz"/"vZ", "vu"/"vU"), assuming they'll be getting format strings as well.
