The fact that the remaining architectures haven't bothered implementing kprobe supposed should not be used as an argument for pushing something inferior out of laziness.
It's the same with syscalls, the kernel infrastructure is there, but if you don't bother updating the syscall tables and wrap it in with glibc, then the call isn't available on your architecture.
The core kprobe infrastructure is available to all architectures, it's up to the developers of the remaining architectures to implement the remaining bits.
