people wouldnt accept 30+ minutes kernel build timesYour enormous hardware budget is showing :) until I upgraded this year I had never owned a machine nor even seen a machine which could build a kernel in less time than that. Multi-hour-long build times are not unknown, though admittedly you need to use 1999-vintage hardware for that, which is pushing obsoleteness even among those of us with near-nil hardware budgets.

You are making assumptions :-)
I regularly build the kernel on stock laptops and desktops (which are typically 1-2-3 generations older than state-of-the-art) and the build times are well below 30 minutes. (usually within 10 minutes.)
The oldest system on which i still build the kernel is a 833 MHz P3 laptop with 512 MB of RAM, there a typical kernel takes 45 minutes to build. (But that's ~5 generations old and kernel developers/testers rarely use such old systems.)
I never build distro kernels though - i always use (and used) .config's tailored to the specific hardware. You can certainly waste a lot of time by building generic kernels.
