from a logistical point of view this really seems to be the best
approach.  keeping all the details in a kernel wrapper of sorts gives
the kernel maintainers much more freedom to make changes in the
future, whereas if its kept in yaboot (rather $bootloader) you have to
deal with backword compatibility and endless luser error due to using
the wrong bootloader versions with wrong kernels.

of course if someone doesn't want to use the wrapper they can just use
the vmlinux and write thier own bootloader to handle all this stuff
and take on the effort of ensuring its up to date with what the kernel
wants.
