Am I right that this conflicts with wpa-supplicant, which is what
NetworkManager uses?  Should this be mentioned?

As a rule of thumb, I recommend avoiding negatives for Booleans; also
add a question mark.

So this would become ‘enable-periodic-scan?’, defaulting to #t.

And it can be ‘boolean’ rather than ‘maybe-boolean’ (the latter would
default to “unset”, whose meaning isn’t clear here).

Same for ‘disable-roaming-scan’.

I would tend to provide a known default value and make it ‘number’
instead of ‘maybe-number’.

The rest LGTM.

Thanks,
Ludo’.
