They are powerful, but if you don't need that power, why pay with the complexity?
This 'extra' copy of things gives you one more place that software can get out of sync (a different version of software on the initramfs than on your main system for example
simple is better, if you don't need a layer of complexity for your systems, it's good to not have it
What's initramfs do now?

cp arch/x86/boot/bzImage /boot/kernel-2.6-linus
Why would I want more complexity to test new kernels?

make install modules_install
which I think beats yours by one line. :)
(Yet again: initramfses *do not* need to be installed in separate files -- distros just do that because it makes it easier to ship prepackaged kernels. If you link them into the kernel image, they don't make it harder to test kernels at all: the installed kernel is exactly one file, just as before. A bloody good thing too given the amount of bisection I seem to have been doing recently...)

It lets you customize things that are otherwise uncustomizable -- personally I consider this a good thing. Obviously it's not essential, but it's not some monstrous terrible hugely complex destabilizing thing either. The smallest possible /init is probably less than ten lines of shell script, and most of that is getting a useful /dev to do a mount from.

How does that keep things in sync? When you update the software on your system, you need to remember to rebuild the initramfs too. Likewise with changing any configuration files that are found in both, like /etc/mdadm/mdadm.conf. I've been bitten by forgetting to run "update-initramfs -u" after changing that file.
