While I do agree that when it comes to editing Vim/emacs/kaoune might be superior, I spend a nontrivial amount of my coding time in 'discovery' mode. scrolling, clicking around, and mouse stuff in general is very useful in that case, and in my experience definitely faster than keyboard-only.

I could try and make a nuanced argument of when and where a mouse is preferable to a keyboard, but I think even just scrolling is enough of an argument for me. CTRL-D or whatnot just doesn't do justice to scrolling with a mouse.

Anyways, mostly I'm a fan of Vim and using its approach as much as possible. I just get annoyed when Vim-fans try to argue that a mouse is never better, which honestly I feel is a the argument of a fanatic. I've never come across a remotely good argument as to why a mouse is never the answer, and it always feels like a needlessly 'partisan' type thing.

Keyboards are cool. Mice are cool. Can we all just get along?

EDIT: I got a bit carried away and I do agree more with you than this comment might suggest. I just think 'editing' is not the only thing I do when coding, and for some of that other stuff a mouse is a huge advantage, even in a coding context.
