I can't understand your reply. Looks like, you do not like the fact that uprobes can be used by the out of tree modules. Why? And why, say, kprobe_register() is exported then? Afaics, it does not have any modular in-kernel user. As for systemtap in particular. I never used it, and probably you didn't. But it has a lot of users, and I know many people who find it very useful.
