Depends on what it is trying to achieve. Based on the Subject: line, it
aims to add support for channels defined in 802.11j and it does indeed
seem to do that (most of those odd channel starting frequencies come
from 802.11y). If the goal were to cover all channels defined in the
current IEEE 802.11 standard, then sure, it would be insufficient, but
it is not like we support 3.6 GHz band or sub-20 MHz channels anyway, so
only the 4.85 GHz starting frequency for some emergency channels from
802.11y would not be covered.
