BEAST has been vaporware for years. Looks like it's finally coming to the market. 20 mills in a single turn benefits the user in that it reduces the possibility of getting lost on a multi-turret design under stress with larger magnum calibers and exteme long ranges past 1000 yards. If the user requirements is built on KISS, a single-turn turret with a zerostop satisfies that principle.
It looks like NF is trying to enter something to compete with the US Optics, Schmidt & Benders, and Hensoldts. Schmidt & Bender has the same one-turn turret option on their popular PM series of riflescopes but their elevation only goes to 13 mils, more than enough for most calibers.
If you want excessive, Carl Zeiss Optronics went with two 18 mil turns on their Hensoldt 3.5-26x56mm
