Literal line cutting is just a special case of separate lines with different processing priority.

Plus, a lot of Precheck people have it via Global Entry, which really is paying to skip the line. Since I got GE, I have never once spent as much time at immigration coming back to the US as it took me to walk from the gate to the immigration hall. Longest line ever was maybe five minutes, because an entire jumbo jet's flight crew was in front of me. I've bypassed hours-long lines.
Though as more advanced scanners come in this might lose value, at many airports now everything stays in your bag anyway, shoes stay on and you go through the whole body scan (which takes 5 seconds). It was amazing how quick it was going through las vegas
In some sense air travel is an exercise in friction and waiting. Standing in line definitely rubs me the wrong way, but others might weight their inconveniences very differently. Perhaps keeping your shoes on should be a separate upcharge from a shorter wait :P
