Is this worth having?  I'm surprised no one has asked for it until
recently...

Are these values correct?  Including the power and gain values?  Does
anyone know have a link to an authoritative source?

This should read:

+	RANGE_PWR(2412, 2472, 20, 0, 0),

The power limit is supposed to be +20dBm in the EU, and it's EIRP so
that includes antenna gain which I've set to 0dB.

For an authoritative document you need http://www.etsi.org but their
site is down just now, so I can't find the document I want.

Mind you, I think France and some other countries still have different
limits/restrictions, isn't ETSI just a sort of advisory body?
