PresentMonService.exe usage model and backward compatibility

[AlexUnwinder]

Can you please comment your view of PresentMonService.exe usage model? Do you see it as a helper service for your internal overlay/CLI applications only or did you plan it as some unified interface and expect third party applications to be developed as PresentMonService.exe clients too? If so, is backward compatibility for PresentMonAPI.dll planned, so future versions of service can be expected to be backward compatible with previous versions of PresentMonAPI.dll?
I'm asking because currently I integrated PresentMon support into RTSS as PresentMonService.exe client, but I'm still not sure if it was right way to go.
