They are using them. Which problems do you expect? The "ClickFinger" mechanism is the only feature of synaptics(4) that doesn't work properly because MT data are missing. Users that prefer synaptics(4) to wsmouse(4) will turn the "ClickPad" option on, activate "soft-buttons" or tapping, and that's it. As to the default driver in wsmouse(4), it doesn't require any manual configuration for clickpads, if you you are happy with soft-buttons (tapping can be enabled). And more and more "newer generation touchpads" provide the full set of MT data to the driver because they conform to the Windows Precision Touchpad standard, which is supported by OpenBSD. Some older hardware drivers provide MT data as well. However, the standard features - soft-buttons, tapping, click-and-drag, two-finger scrolling - can work reliably without them, even on clickpads. Some more or less subtle aspects of their behaviour - like pointer control - will depend on the device firmware. Only some "newer" features, like "thumb detection", won't work.
