perf *is* an exception today.

It might make sense to change that. But IMHO it only makes sense if
there is a really broad agreement on it and other core stuff moves into
the kernel too. Then you'll be able to get advantages out of it. For
example standardizing the process to create an initramfs (using the
userspace tools shipped with the kernel) instead of having each distro
creating its own way.

I somehow doubt we'll see such an broad agreement though. Most people
seem to be happy with the current model. There is a reason why the
klibc + early-userspace-in-kernel-tree project died in the end ...
