All linux libc's do this. glibc, dietlibc, and uclibc.
Beyond this if you really object you can come up with a set of header that just describe the kernel/user space ABI, and build them so either the kernel or user space can use them. And then this ABI-headers package can be used to hold the common definitions.
Until someone builds a kernel-abi-headers package everyone will do it by copying the appropriate headers periodically.
