Do we know what we want to do with this gesture? Because if not I'd
rather not merge it for now, until there are real users.

And do what instead?
Report 5 fingers with BTN_TOOL_QUADTAP?

That, or nothing... The fact that the device can report 5 finger touch
does not mean that anybody cares about this.

The uTouch gesture stack supports up to 5 touch gestures, and although
most of them are either hard to do on a trackpad or are not possible
with this driver, I can think of uses for 5 finger tap. Unity uses four
finger tap quite effectively I believe.

There is a meaningful limit to this: five fingers on a human hand. It
seems more arbitrary to stick the protocol limit at four fingers.
