Now 15 years later I really enjoy the flow of the layout, a majority of the time when typing you alternate between sides of the keyboard when typing and it just feels good.
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.
Why not just remap? My intuition is that the cascading conflict wouldn't be that hard to resolve (at least compared to learning Dvorak...) but maybe I'm wrong.
Forgetting to configure computers after finishing with them, not knowing what layout was in use in the login screen, initial configuration, etc all cost time. I also use RDP a lot which is layout roulette (sometimes it changes, sometimes it doesn’t)
