They did exactly that at MSP (Minneapolis/St. Paul), almost literally.
They recently consolidated the checkpoints from 4 down to 2. No one knows why, but they did. Security immediately went from 30 minutes to 2 hours. They blamed everything from funding (which they received $91 million more than they asked for in 2016) to people's bags (which somehow changed overnight). When the local government and our fed reps complained, one of the people they sent to respond was a promoter/marketer specifically for pre-check.
One time I went through, PreCheck was being hawked actively. Random people were getting automatic PreCheck allowances on their boarding passes so they could "try it out". Very commercial vibe around that.
This happens all the time; I've gotten it quite a few times. I always assumed it was just to randomly lighten the load, but the commercial thing makes a lot of sense too.
My pro tip is to fly sun country - you go from the international terminal in SFO to the HHH terminal in MPLS, both of which are nice, clean, modern and underutilized.
