I think that we often forget that these vehicles were designed to operate at temperatures as low as -65°, that's 65 degrees below zero. It is very possible IMHO, that odd features like oil filter canisters that drain into the oil pan after engine shut-down are part of this general requirement.
The Arctic kit has an oil pan shroud, which will heat the oil in the oil pan as the coolant heater heats the upper portion of the engine.
If the oil remained in the filters, it may not flow at all.
Today's military vehicles are riddled with compromises and the operation at temps below minus 25 may not be terribly important. For example, the CTIS feature is not supposed to be used below zero even, while the deuces, including our beloved multifuel engines, were designed for the full mil spec temp op range.
So, when we make changes "for the better", we often don't think of the extremes of operation.
