It isn't really a matter of time. It's a matter of putting only the
necessary code in the kernel.
Sure, we could put code in the kernel that removes modules like kerneld
did (this was done in the early kernels with kmod: see 2.1.90), but
there's no advantage to putting it in the kernel. The exact same
functionality can be provided by the exact same code running in userspace.
See the code for kerneld, it just has a loop that runs
delete_module(NULL) every once in a while (effectively the same as running
rmmod -a).
