not writing to the syscall table hasn't been possible/allowed for..
about 5 years now. (yes I know there were still bad hacks possible
until 2 years ago). So I'm sorry, but the timeline argument doesn't
hold, you've had 5+ years of warning.

All existing RHEL products already don't allow this (I know it for the
earlier ones since I was part of the design team)...  unless your
software acts entirely like a rootkit (but even then)
