J and K are adjacent in Dvorak, and they're down and up, respectively, which makes vertical scrolling just as easy, IMO. I never really used H and L but instead rely on mostly W and B (which aren't adjacent but are close enough). So by happy coincidence, navigating in vim works just fine, I think.

Yep, I've never felt the need to remap hjkl for other layouts. Very exaggerated issue from people who didn't stick with it long enough, I think.

I was worried about it with Workman because it was slightly less logical. h still left of l, but quite far away, j and k are placed so that it's like you've inverted your camera controls in a game. Very easy to adjust anyway and I don't really think about it now. Your point about w and b is very good as well. Advanced vim users are actually less likely to use hjkl much due to having faster ways to get around in most cases.

Yep. I use vim & evil regularly with dvorak. J and K as well as H and L are just fine. H and L are placed very similarly to where they are on qwerty; H is just shifted one position to the right, and L is one position to the right and up. So they still have the "left-right" feel, and I like that H is under the index finger.
