Ehh I kinda hate the touchpad on the DS4 ...found it too gimmicky in Infamous. But to the OP, I don't know if you follow GIMX? But he made some headway on it, XIM may do something similar ...but so far it's commands in most games seem superfluous
I definitely agree the touchpad is a bit silly but if you (and I'm using Infamous: Second Son as an example) can't use the touchpad to absorb energy, open cells, break autoguns, etc then you're kind of screwed.
We definitely need some way to map different combinations (e.g. push the touchpad down, swipe left, right, up, or down) to be able to play some games.
What are the beta testers doing right now?
