I must say this is quite ugly, but so is introducing ABS_CONTACT_COUNT
or similar, except that the latter is more extensible so if
manufacturers decide to report 6, 7, 8 fingers (but not their
coordinates) we won't have to breed BTN_TOOL_xxxTAPs...

But let me ask you this: do we know what to do with 5 fingers? How do we
plan to react to such gestures? Maybe the best option is simply ignore
it and don't report anything if there are no userspace consumers?

Thanks.
