This method is for customizers more than generalists today. but
should potentially be extended to generalists tomorrow (this method is
similar to what I would refer to as "pimp my PC").

/boot/loader.conf is empty by default. GENERIC for the most part
is a complete, monolithic kernel. I'm not sure what the issue is here,
because this is for more advanced usage (i.e. you do linux_load=3D"YES"
in /boot/loader.conf, etc).
