I think you need to explain in detail why you consider this a problem.

With LD_PRELOAD and LD_AUDIT, you can already do anything, including
scanning other loaded objects for a system call instruction and jumping
to that (in case a security module in the kernel performs a PC check to
confer additional privileges).
