It's really down to the writers of the standards.
They take an existing standard, and as technology advances, they update to still cover the old tech and add in the new tech, and try to account for the differences in the best way they know how. Which is usually not very well.
As the new technology (the electronics bits really) is so different from what you had before. So when the old tech drops out of circulation you are left with rules that don't really apply, or are written so vaguely that you could drive a bus through the loopholes.
Doesn't help that a lot of homologation standards are written by the people involved (drivers/committee members/keen parents), who gather a lot of information from reviews and manufacturing blurb, with a smattering of technical data, rather than being written by people who write standards.
Whats needed is a wholesale rewriting, from scratch.
(i deal with homologation standards written by government committees, they are far far far far (far) worse than the BRCA/ROAR/etc standards, and have long lasting (negative) impact on what we are allowed to do.)
