I can see one advantage of product-specific standards. They are generally, but not always, easier for a novice to apply them correctly. The product-specific standards cover the hazards of that product in detail and typically require less engineering judgement or analysis. This may be helpful on a product such as two-wheel self-balancing scooters where many manufacturers appear to have little experience with safety certification. (I refuse to call anything that doesn't hover a "hoverboard".)
There are clearly many disadvantages of a product-based standard in comparison to a hazard-based standard. New design methodologies or technologies may already be adequately covered by a hazard-based standard but need to be incorporated into an existing product-based standard. Hazard-based standards give designers more flexibility and can make innovation easier. A hazard-based standard covering a wider range of products reduces the risk of having differing requirements for similar product types. This is only a short list. It may be that the authorities that be decided that they wanted a step-by-step guide on how to make these scooters safer and a standard specific to the scooters accomplishes this task better than proposing an existing standard.

I envision a standard for each energy source, for example electric shock. Electric shock from a toaster, or cooker, or microwave, is the same as electric shock from a TV, or computer, or voltmeter. This is largely recognized in the various 335 parts by reference to 335-1. So, you take the electric shock requirements from 335-1, and add generalized electric shock variations from each of the 111 parts, and you now have a standard for electric shock that covers all 111 parts. And you examine other standards such as 61010 and incorporate any new requirements. Presto, you have an electric shock standard. Not particularly time-consuming. The big problem is that each one of us has our favorite product safety standard; we are not willing to give up the familiar requirements -- even though they may be the same in different words. A second big problem is that few of us have applied engineering or science to the field of product safety. It is much easier to write a safety standard based on "inversion of bad experiences."
