That’s a fair argument, thanks for showing me the other perspective!

Imho, I prefer an editor that focuses on doing editing right, and provides the interface and APIs for integration with other things. I get the appeal of built-in LSP working OOTB, but I prefer this gets done by distributing the a good editor pre-packaged with LSP and other plugins, sort of like how you get lunarvim or nvchad as neovim with config and plugins ready. This way you get LSP out of the box, but others can customize if they need.

helix […] shares kakounes keybindings and input system

I get that it is inspired from it, but it felt like a strange in-between to me. It still has 3 modes, and the two non-insert modes seemed not to have a well-defined boundary. It didn’t just click with me. Kakoune seems to do it much better imho.

You can do this [shell integration] in vim and helix as well

I know vim has some basic she’ll integration, but it is not the same as Kakoune’s, unless I missed those features in vim and helix. I don’t wanna duplicate things, so I recommend you read the shell section of this page: https://kakoune.org/why-kakoune/why-kakoune.html
