The one argument against them, that I agree with, is Linus' hooks to
avoid the GPL.  A binary only module could easily add their own hooks
into the kernel.

I've made this patch with the option to turn this off. I should have put
the option in Kernel debugging with the default off (the default is
currently on so that if you apply the patch, you have it automatically).
This way binary only modules can't take advantage of the dynamic
syscalls without recompiling the kernel.  If the user needed to compile
the kernel, then a patch can easily be added, so this is just as good of
a defense.
