no, I'd rather not make this a default. I'll add an example to the default config file but people use their touchpads quite differently and we can't tell. specifically, we configure the soft buttons to work as left/right on non-apple clickpads but a user who enables tapping is less likely to use the buttons. disabling the area for those users is a regression.
