Not sure if I followed what you said. What I mean is that isnt hitting the spacebar 4 times more difficult and annoying than hitting the tab key once ? Yes you can configure tab key for any number of spaces but still the point being about hitting spacebar multiple times.

Modern editors generally don't require you to hit space four times. There's a "convert tabs to spaces" option so you can hit the tab key, and most of them do auto-indenting anyway.
