It was brought up in thread but not stated as strong requirement. BTW, there are patches in last couple months to x86-input-synaptics that will allow it to ignore jumps in values of ABS_X/ABS_Y when transition of multi-touch occur (both adding or removing fingers via BTN_TOOL_*TAP). So one new-ish option is for ABS_X/ABS_Y to not track 1st finger but become average of 2 fingers.
