Easy enough to have a drop/windage chart w/10MPH wind calculated. Wind is linear. Cut in half for 45 degree angle or 5MPH full-grade, double for 20MPH full-grade.

I cannot fathom being afield without a backup chart afixed on-board the rifle somewhere. Under the scope cap, taped/velcro'd to the stock, I've written the data I needed onto grey paint with a black sharpie. If your LRF somehow dies afield at least a hunting partner or your guide can give you the range, then you can consult your chart and make the necessary correction. We're not talking about hauling a 20" cast iron skillet to a mountain top, it's a piece of paper smaller than a .50 cent piece.

I certainly agree with all that, but thought I’d point out that wind drift is linear in wind speed, but non-linear in direction. When it comes to wind direction, full-value drift is multiplied by the sine of the wind angle (assuming a headwind is coming at 0 degrees), so a 45 degree wind actually gives roughly 70% of the drift of a full-value wind. Half-value wind is actually given by a 30 degree angle.
