There are still a lot of developers out there that basically are at the hammer and nails level of programming. They use a basic editor with basic syntax colouring and when they write broken grammar, the editor just misbehaves telling them they've typoed something.

Many still use rg and fd or fzf outside or within their editor and are anti IDE.

I think ultimately they do waste time, particularly they see refactoring as a big 4 hours job when people using intelliJ and other proficient IDE will see it as a 5' job.

That said, have you every felt, that using all the bells and whistle, half the time you're being impaired by them? Auto-complete nags you, copilot is completely off the plot and spewing tons of stuff all the time.

The key, I think, is to have all the bells and whistle but have shortcuts to turn them on/off. I have auto-complete only drop down on ctrl+space shortcut, not automatically. And for copilot, I have ctrl+cmd+c for turning it on or off.

That way I can free flow type code as I think of it and get the tools to assist whenever needed. It's the best of both world. The IDE as clutter free as possible, and all the tools at a finger tip.

But renaming symbols throughout large projects without an LSP? Nah, been there, done that, for decades, and I'm glad that's over.
