This option should really be used by OEM/ODM that have assured proper certification or scientists using a shielded room. Distros should be strongly adviced not to use this as their users tend to be unaware or the distribution ODM / OEM may not have done the necessary work to ensure proper regulatory certification. Perhaps we can clarify that there is a heavier onus on regulatory certification if these options are enabled. Linux distributions may be eager to please their users, but I would expect them to have common sense as well. We would just have to educate them about this option. As for a name, I thought about it for a while and given that we have different "wireless" technologies -- bluetooth, NFC, naming this CONFIG_WIRELESS_EXPERT seemed odd, and given that our 802.11 framework is under cfg80211 naming it CONFIG_CFG80211_EXPERT seemed appropriate. But even if its under cfg80211 perhaps something more explicit about the implications may be better, how about CONFIG_CFG80211_MAY_BREAK_CERTIFICATION ?
