I'm pretty sure that at least the security_ops function pointers could be
resolved statically with some proprocessor trickery right now.

E.g. define macros for the security_* hooks in the single security module that
is configured statically and include those defines in security.h instead
of the prototypes for the inline functions. Am I missing something?

If a distribution enables such an option there is no way to load a
security module, true. This is what we have right now if the distro disables
loadable module support or disables security modules.
