This is the height of arrogance and shows a lack of understanding of what user ABI requirements are all about. It is possible for other userland components to be built by other people, outside of your controlled eco-system and tools, that use these interfaces. And you cannot control that. Therefore you cannot make arbitrary changes to UABI data strucures just because the tool you use and maintain is not effected by it. Please stop making these incredibly incompatible user interface changes in the RDS stack. I am, from this point forward, going to be extra strict on RDS stack changes especially in this area.
