> Those are by far the most important features for a text editor to have

To you, maybe. The most important features of an editor for me, and for many people, is that it is stable, dependable, and ubiquitous.

There is no way I am going to re-learn years of muscle memory for a "post-modern" editor. Cool and trendy is the exact opposite of what I want in my tools. What happens with the authors get bored and move on to the next shiny thing?

Vim is available on ~every machine I could possibly interact with. There is a vim mode in every single mainstream editor / IDE. My Vim muscle memory will keep me productive for the rest of my life.

IMO, making something slightly nicer to configure is never going to overcome the inertia of a project like Vim. The new editor would have to be like 3x better to convince everyone to make the switch, not 1.1x better in some specific areas.
