No.  It can be configured out of the kernel, and a number of small
distros do this because it adds considerable overhead.

What is wrong with doing this the right way, like I said in my
previous email?

... and you shouldn't depend on specific details of kernel internals
(although TBH 'cleanup_module' seems unlikely to change since it's
been named that since Linux first had kernel modules).
