It seems to me that for the folks who live in more temperate climates, have gravel driveways, and get light snows (under 1ft), that a rear blade with gauge wheels would be great for snow removal.
Set it about an inch or two above the surface, drop the 3pt, pull the pin on the angle (pitch?) setting to let it float side to side, then drag it through the snow with some speed removing the snow but not the gravel.
Alas, none of the rear blades I see for sale have gauge wheels except for the high end hydraulically operated ones. Landscape rakes come with gauge wheels, why not rear blades?
