Can you describe said shooting of foot? Because...
+ I still build my kernels that way, because...
+ config can be given -C to retain the *entire* config file in the kernel, comments-and-all, because...
+ There has traditionally been no knob that can be set during the kernel targets of the top-level Makefile that will enable "config -C" instead of just "config".
We use a version-controlled config file and want lines like "# $Smule: ... $" retained as well as include lines, etc so we can see hierarchical topology of the kernel config from a running system in the field simply by running "config -x $( sysctl -n kern.bootfile ) | less"
Thus, I wouldn't even call this a "FreeBSD 4.x [process] of bulding the kernel" but instead "an alternate proceaa of building kernel" and the people that use it know what they are doing and this there is no foot shooting.
NB: I actually use "config -C -g" for full disclosure.
