I'm not arguing that Kakoune's way isn't better (I think it probably is). But you can sort of do this in Vim as well, minus the more advanced interactive adjustments:
- :set hlsearch
- Type `/`
- Spend five seconds thinking up a regex that approximately matches the things I want to change
- Hit Enter
- Cycle through matches with `n`/`N`, checking to see if they're what I expected
- If they're not, press `/` then <Up> and edit the regex
- When satisfied, type `:%s//`, enter the replacement you want to make, then `/g<Enter>` to apply the change everywhere
- :set hlsearch
