Is it though? I honestly don't understand what the big deal is. The original contention was that the benefit was in offering selection-then-action, unlike Vi. And then when it's pointed out that Vim actually offers selection-then-action as well, there is a new assertion that it's the particular WAY that Helix offers selection-then-action that is key.
To my mind, selection-then-action is provided by Vim if you want it. Maybe it's a few extra keystrokes sometimes, because it's not the default mode, as it is in Helix, but the main concept (ability to think in object-then-verb) is available in both, if that's the way you prefer to think.
