While one could set options in the kernel to affect the ufs.ko build,
there’s not a universal ufs.ko that can be loaded easily that switches
between the different types of options. You can create modules
that do this, but that’s a very very different problem than the one I
want to solve, namely you get the same[*] functionality having
device fred in the kernel config as kldloading fred.ko. So rather than
bite off that problem also, I’m opting for simplicity.

OK.

These are already the default for the ath or wlan modules, if I’m reading things correctly.
