When David Musgrave departed Microsoft, the future of the Microsoft Dynamics GP Support Debugging Tool (SDT) became uncertain. The tool, and David's long time support of it, was generally considered a source of tension to some degree inside of Microsoft during his years there.  SDT wasn't an officially supported product and it received little support beyond Musgrave's own efforts. Yet SDT gained a loyal following among GP users and professionals who valued the various capabilities, giving Musgrave some space to continue supporting and updating it over time.
