I suppose it makes less difference on a modern system where "make buildkernel" takes 15 minutes or even less, but the manual kernel build gives the opportunity to rebuild a kernel without building everything --- as in the case where you just modified something simple (say USB or PCI device IDs). I'm not talking about the dedicate kernel developer who should "know things" like this, but the user who makes these kernel modifications occasionally.
