Well, Lisp code can't be properly indented with just tabs. So tough luck, I guess? Why wouldn't editors programmers use allow to customize indentation space size instead? So you could set up each indentation space = 2 characters and get huge indents. Or set it to 1/2 character and get tiny indents. Seems easy to implement in e.g. Emacs.

Why can't it? Fixed width tabs, sure, but tab stops would work fine.

It is more work in the editor, so I don't expect it anytime soon. Especially not with consistency. But it is doable.

Also, you couldn't possibly follow ruby's style guide with tabs:
