My comment was limited to EMC and product safety. I didn't state that, but that was my frame of mind. I don't think technology here changes that fast. Clearly you have extensions of spectral usage so over time your radiated emission/immunity control increases in span, but in the regions where control is already exerted I don't see the need for constant change. And immunity threats are what they are, you don't change them annually because of changing technology.
