Yes, exactly right. The vast majority of programming is editing code, and cursorless allows you to A) Navigate code quickly and B) do things using less navigation than you could with Keyboard/Mouse.
I am a cursorless user myself. Using dictation software for programming is actually relatively fast when you get used to it, but editing code (which is how most of us spend the majority of our time) can be pretty slow. Cursorless was a huge productivity booster for me. It got me to switch from Emacs to VS Code which is saying something.
