Because I missed that we have a kernel side knob as well? Though please
read on...
I'll look into it if it is indeed so but on a quick glance in man
src.conf you would want WITHOUT_WIRELESS_SUPPORT.
man src.conf
WITHOUT_WIRELESS
Do not build programs used for 802.11 wireless networks;
especially wpa_supplicant(8) and hostapd(8). When set, these
options are also in effect:
WITHOUT_WIRELESS_SUPPORT (unless WITH_WIRELESS_SUPPORT is set
explicitly)
WITHOUT_WIRELESS_SUPPORT
Build libraries, programs, and kernel modules without 802.11
wireless support.
But neither of the WIRELESS[_SUPPORT] knobs seem to be applied anywahere in
sys/modules at this point, so iwlwifi is no special but all kernel wifi
modules would be built.
% grep -r WIRELESS sys/modules/

Because it is a non-essential driver to boot and so we only build it as
a module which is a continuation of that people once started in order to
get GENERIC size down. The module will be loaded at run-time
automatically (in a default setup) if such a card is found in the system
and the driver will then automatically load its firmware (which will
hopefully eventually also not be in base anymore).
