> But I still like my git config, my editor and other tooling that I have to assist in my tasks. And it's not worth it to replicate it over to other people's setup.

This isn't about stopping you from customizing your development environment. It's about making your custom development environment automatically useful on your desktop or your laptop, or committing a project-specific starter environment to version control so that it doesn't take everyone on your team days to onboard.

> And neither I want their things.

Why not? This isn't about something like git aliases or editor keyboard shortcuts. It's about tooling pipelines. If someone's claiming enhanced productivity I don't want to watch their 1 hour youtube video, pause it, and painstakingly recreate their setup to check if the claims are true.

There's a reason projects grow Tiltfiles, compose files, and similar. In the limit, agents are basically just a collection of microservices that just happen to operate on code. How do you expect to do that sort of thing without tools?
