Seems to me, the boot is a preventive measure for "extended" interval where buildup usually gets neglected for a long time. for a street car, I imagine the brake piston spends months/years extending out to compensate for the worn pads. I would want boots in this case.
For cars that visit tracks, things get changed and cleaned frequent enough to negate the negative of the missing boots.
