It's good at least in my case because I switch between Dvorak (Corne) and Qwerty (laptop's keyboard) all the time, without positional keymap, I would have to develop two sets of muscle memory

The effective freedom to choose keyboards like Dvorak relates directly to the privacy of a remote vi not breaking the privacy layer of this abstraction. Do what we do because the servers won't be updated or we will specifically lock their choices, etc..

After a few years of trying to get along directly in local pair programming or similar with people with local largely insane keymaps I decided to make use of fences and privacy making good neighbors and I don't want those fences ruined.

Even without my intended uses for this abstraction, positional habits is the first step of getting people out of the crib, a crib is easy to sell a start in but not a place to retire.

Helix OTOH looks good.
