Umm, folks.  systemtap basically means people compile kernel modules
from an odd scripting language with embedded C snipplets into kernel
modules.  The kernel modules don't use normal exported APIs but use
kallsysms and dwarf info to poke into every possible private bit.

Saying you don't care the slightest whether oracle will load huge
amounts of code into the kernel that depends on intimate implementation
details, and that you don't even have source to to debug it is not what
I'd call "none of us need to care in the slightest", at least for those
of you working for distributions that may actually have to debug this
shit in the end.

While we're at it, what happened to the idea of tainting the kernel
as soon as krpobes are placed in the kernel to at least make people
aware of it?
