The Rules Compendium goes beyond errata as it includes rules from supplements such as the Environment series as well as new uses for skills.
Don't think of it in terms of redundancy. Of course it's redundant. The value of the book comes in its presentation and layout. The table of contents and index are very thorough, and the book pretty much presents one rule per page with some exceptions.
Additionally, the book offers much better clarifications for rules such as line of sight and line of effect with full illustrations to help better understand such things.
As an example, the Rules Compendium makes it so much easier to find rules about flight movement without have to cross reference the PHB, DMG, MM, and Draconomicon. Same can be said about effects such as invisibility, spot checks, lighting, distance, etc. It's all right there for quick and speedy access.
