The course was originally a distinctive specialty for the UK. It was a response to the fact that most at UK divers need to use DSMBs, and at one point, it looked possible that DSMB might become mandatory for UK diving.
Whilst many instructors did include DSMB in open water, and/or subsequent courses, many didn't. The distinctive course gave ample opportunity for divers to seek dedicated training on their use. This was especially important as UK accident statistics (BSAC annual reports) illustrated that a significant number of DCI / rapid ascent issues stemmed from improper DSMB use.
Recently, PADI converted the distinctive version of the course into a standard specialty, available worldwide. It's a valid course, as there are thousands of divers who've never received formal training on DSMB use. It's also a simple course, teaching simple techniques that make a common skill safe and efficient.
The actual validity of the course is, of course, entirely instructor dependent. As with many courses, the expertise and knowledge of the instructor dictates the attention-to-detail and best practices introduced. Naturally, some instructors will teach better, more skillful approaches than others. I'd suggest that instructor well-versed in sound technical diving procedures is more likely to offer quality instruction.
