Side note: if people want to, we could have other "trampolines" like that, so that we could have more user-level code that gets distributed with the kernel. It doesn't have to be something that gets mapped into every binary either: we could - if we wanted to - have things like shared libraries or helper shell scripts or whatever that we expose in /sys/shlib/ that are kernel-version dependent.
Then we could perhaps change more things, just because we could change the wrappers that actually use them together with the kernel.
To some degree, /initrd was supposed to do things like that, and in theory, it still could. However, realistically, 99% of any /initrd is more about the distribution than the kernel, so right now we have to count /initrd as a distribution thing, not a kernel thing.
