That I debate. :)  Having a bikeshed on arch@ might let more people know about 
it, but documenting things doesn't always make them more widely known.  
There's a reason they are called FAQs.  Also, the intended audience for this 
target is mostly developers, and they probably already know about nextboot.

The confusion there is that he is using installkernel from /usr/src/Makefile 
which does a full kernel install including modules if needed.  I'm not sure 
that this target is really a good idea given reboot vs. shutdown as well as 
using nextboot options (I would probably want to use nextboot -o "-s" -k test 
most of the time since I usually like to boot test kernels into single user 
so I can do simple testing before I unleash it on multiuser) means that by 
the time you add tweaks and hooks for the various different options you 
really haven't saved much typing.
