As everyone has said if you have plenty of white cedar I think it is a decent idea, hinging them may be even better keeping the trees alive for a couple more years of food.
We normally don't get snow very deep for long down here, my area is almost devoid of any conifers except for red cedars and the deer don't seem to touch them for browse. The white cedar and white pines I put out are browsed hard in winter even with no snow.
I like sandburs idea of planting some shrubs specifically for future browse for the next hard winter.
