Impurities= uncertainties. TMPs are not a good place to cut costs, imo.
I know, you get into a question of purge costs vs TMP costs… but it might be a discussion worth having.
I agree, could lead to the good, better, best, bestest, most bestest marketing strategy. I used to work near vacuum pumps (not TMPs) which could quickly put a serious vacuum in the FF chamber. They are anything but small, light, or cheap, they make a lot of heat, and need at least one overhaul per year. I hate to imagine what all the specs are for a Turbo Molecular Pump that could handle even a 300 hz trigger rate.
I have a hunch this can be answered in the scientific, engineering, manufacturing, and marketing mindsets, lol.
