The safest quirk for a device (the one that works out of the box for most of them) is MT_QUIRK_NOT_SEEN_MEANS_UP. Indeed, it does not make any assumption on the device. When adding a new device, we can easily test it against MT_CLS_DEFAULT, and then optimize it with other quirks: that's why no device use MT_CLS_DEFAULT right now.
