This would arguablly represent an acceptable trade-off against the risk of wind blur with longer exposures!

I'm shooting an 8x10, normal lens is 300mm, with occasional 19" and 210mm. I can rarely use much tilt...the "foreground" is often a tree close to the camera that goes from the bottom of the image to the top...or close branches that extend into the upper corners of the image Front tilt just throws the top of the image way out of focus.

I know what you are getting on about, but that sort of image is out in the open...rarely deep in the redwoods. Using a lens wide open or at f11 would be wasting film (if one wants good focus throughout the whole image).
