That depends on the use case.. If there is a huge number of specific
SSIDs to scan for, reducing the maximum number of SSIDs from 4 to 3 per
scan request has significantly more impact than moving from 16 to 15
would.. That said, I don't think this is really that significant an
impact in practice even with a limit of 4.
