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.
