Ah, I see. My process has always been:

cp arch/x86/configs/foo_defconfig .config
make oldconfig
make obvious decisions about new symbols, choose defaults if unknown
diff -u arch/x86/configs/foo_defconfig .config
figure out if any decisions or defaults are incorrect, change accordingly
make oldconfig (more decisions if there are new symbols exposed)
cp .config arch/x86/configs/foo_defconfig && commit

My build has broken again, which is why I'm inquiring about the status
of this; I'm not going to bother fixing it if my patches are never going
to end up upstream..
