This "standard" exists for the sake of code analysis vendors to be able to have some sort of shared taxonomy, but also provide a fig leaf of standardization to their products.
Personally I've always been a proponent of project specific standards, but after many years of discussions about more or less individual preference I've come to think that maybe settling on something global isn't the worst idea. Not that I think it must be this one in particular, but it's not the worst start either.
