Unprotected Hardy BLEs need protection, too

Over the years, I must've heard many discuss how they don't protect, or need to protect various palms, and the like. |
Well, while out shoveling snow today, I noticed some foliar damage on my Rhododendron 'Capistrano'. This is supposedly a very hardy cultivar of Rhodie (down to z4...-20F to -30F range). Gosh, my minimum was only in the z6 range. A few days ago, Tom in Pa, posted a pic of a boxwood (hardy down to z5 minimums...-10F to -20F), in his yard, that also had foliar damage, while posting something a bit more exotic to his zone. Yesterday, Fred posted a pic of his Sago, in which the foliage was fried, after z8a minimums.
My Capistrano is in a more exposed site, more like Tom's boxwood, than my boxwood, which has no foliar damage, at the same z6 minimums. I guess, some burlap around my Rhodie would have prevented the burn, or at least, if I had completely covered it, with snow, just before the blast began, the foliage would have remained unscathed. I hope the flower buds, set last summer will be ok.
It's funny how we could focus so much attention on protecting exotic plants (or worry if a polar blast will cause damage to our palms), but show no attention to ALL broadleafs and conifers, in our yards.
Why is that?
I have seen "bone hardy" conifers, like Colorado Blue Spruce, and Arborvitae, planted as screens, next to well-travelled, "salted in winter" roads, suffer serious, irreversible foliar damage, from the salt spray, which can be like that sustained by some beach plants, that are salt-intolerant.
I think that if BLE plants can't be given better siting, then some protection is needed for ALL of them...at least, in z6 minimums, between 0 and -10F.
