Linus' opinion on "what goes into the kernel and what doesn't" is
that what CAN be done in userspace, should go in userspace.

MOST users won't want this undelete stuff. If they DO, then they
should configure the extra libc-with-undelete.whatever.

That libc should also provide a symbol called for example
"real_unlink" to use the system call....
