This is nothing to do with udev or the kernel side of things. Your
argument seems to be

"Remove a user space problem and make it a kernel one stuffed in
 unpageable RAM and less flexible"

It seems to me your actual problem is "my tools suck" and the fix for
that is to fix the tools not add more random kernel junk.
