Meanwhile there's always a community of vim and emacs users who build all the internal integrations by themselves. Vim and Emacs aren't editors, they're platforms and communities, and the benefit of using them over VSCode of JB is that you get to be a part of these communities that attract the best talent, give the best troubleshooting advice, and share advanced configurations for everything and anything you could possibly ever want. They are programmable programming environments first and foremost, and that attracts people who are good at programming and like to hack on stuff.
Technologists who choose the propriety path of least resistance when it comes to their most important tools I think are ultimately missing out in a lot of ways, least of all is the actual editing experience. A craftsman should understand his tools inside and out, and picking something you can't fully disassemble and doesn't have the breath of knowledge a tried and true open source tool ultimately becomes just as frustrating as the initial learning curve of these older tools.
