Sorry for commenting on a closed bug.

I hacked tap.c to add 3fg dragging support:
https://github.com/tigersoldier/libinput/tree/wip/three-fingers-dragging

I agree doing this in compositor is more flexible. OS X seems to treat 3fg
dragging and 1fg click dragging differently. One difference is that 3fg
dragging on selected text won't trigger dnd. It unselects the text and restart
a new selection.

However, I wonder how dragging lock can be implemented at compositor level. A
simple timeout won't detect any taps between two 3fg drags.
