Who decides if a given technology makes 'efficient use'? For example, simple AM could be disallowed because it's not as 'efficient use' as 16-OFDM. I am concerned because a certain novel technique may quite possibly be unusable in Europe because of this 'efficiency' provision. With best wishes DESIGN IT IN!

One example, would be a TV viewer hoping that their TV might still work whilst they're sat 2m away accessing the internet using a 700 MHz band LTE mobile phone. This problem didn't exist in the 1990's when the R&TTE directive was written...

Article 3.2 of the R&TTE Directive requires: radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/ space radio communication and orbital resources so as to avoid harmful interference. Article 3.2 of the Radio Equipment Directive has an additional requirement in that it requires: Radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference. Article 3.2 Harmonised Standards are effective mandatory as any manufacturer not wishing to apply them in full must obtain a Notified Body opinion and the Notified Body should really consider Harmonised Standards where they have been published.

It could even be challenged as a restraint of trade. But I expect it will be nodded through. With best wishes DESIGN IT IN!
