Stepdown leaf springs

in HUDSON
Is it advisable to actually grease the rear leaf springs between the leaves themselves on a Hudson stepdown besides the rear shackle bushings?

The host of the event had a vintage tool that's used to spread the leaf springs, as the car's rear axle is hanging above the floor, to allow grease to be injected into the gap made by this tool. Several of our members present mentioned how important it is to grease the leaf springs themselves. This was news to me having never done that before on any car I owned and therefore I thought I'd seek some additional information via this forum.
Yup they are called either "Spring Covers" or the slang name "Gaiters".
Metal covers were seen in the later years of their use (late 40s early 50s) in the 1920s and 1930s they were leather that was cut and sewn to size and they were then laced in place.
Pretty standard on luxury cars (CCCA Full Classics) they were also offered as accessories on lessor cars. (In the accessory catalog for the Ford Model A)
In the world of judging big classics there is a point deduction for not having them.
