For sure, I'm saying that vi stuck with its design rather than follow the trend of other modal editors that converged on one insert mode, and so did its follow-ups like vim.

I just tried out helix and I'm really liking the features like its single insert mode. Still taking some getting used to, since it's selection-first, not command-first, so `dd` just deletes two chars and not the line. And shift-V doesn't select lines... grr.
