They have! I use a Jetbrains editor daily and I'd never be able to work without it.

Look under Edit > Column Selection Mode. I think it's bound to Cmd+Shift+8 by default.

If you have a set of lines selected, it will transform them into multiple individual selections too.

I don't remember what "Edit Each Line in Selection" does, but JetBrains does have vertical multi-line character selection. Same as in TextMate, hold down alt, click and drag the mouse to select a rectangle. The JetBrains version sometimes feels less polished than that of TextMate but it works well.

Have you tried VSCode? I believe it has this as well. And Sublime.

And Emacs (C-x r t), and Eclipse (Alt-Shift-a to switch to rectangle mode).
