Yeah, the interview basically said they are working to figure out how to get arrivals without going through security again. CBP would still be necessary, and yeah, I imagine it would be something like how pre-clearance works and just have dedicated channels where you can either exit or go directly into the terminal. As this was a TSA interview, it was pretty much exclusively about security rather than CBP. Though it might be a bit annoying if you have GE and get off the plane right away to have to wait for bags to be photographed, but still less of a wait for them to get out onto a belt, so better overall.

IIRC, there was also talk of EU removing the US from clean arrivals countries because there was no work being done on making it reciprocal where airports like AMS or ZRH allow US arrivals to not clear security at all.
