I think this is a good point. The company I used to work for had a different hierarchy that people would get promoted within but it was never made clear a) what you had to do to get that promotion and b) what sort of pay increases got you there. It was a small company that grew into a medium-sized one (30 to 150 people in four years) but any discussion of more formalization or salary bands going forward was poo-poo'd as being "too corporate". This despite any time annual reviews coming around and there being a round of promotions that would kill morale the following week.
