I gave that a try and it seems pretty amazing to me... the terrain looks way better and the blending is much more as I would expect. I definitely think this should be the default.
For some reason the terrain painting tools are a bit broken for me... the mouse movement seems inverted which is weird. Probably not related to your work though.
I do find the distance texture still lacks any sort of detail at all though once you get past the 100 range the detail texture is set to and increasing the detail distance just makes it look obviously tiled. I would like to see a bit of detail, but not as heavy as the up close... perhaps we could have a fall off setting on the detail texture?
So say your detail texture is now at 100 distance with falloff being 0 (default, same as it is now). If you set it to 200 with falloff 0.5 then from 0-100 it will be at full power and then get gradually less powerful until reaching zero contribution at 200 range. That way the land 180 away will have a subtle amount of detail rather than just looking blurry.
