These interfaces are broken for about 9 months, maybe longer than that. At this point, this is just a dead code nobody tests or tries to use, so let's remove it instead of keeping a stale code just for the sake of keeping it and hoping someone will fix it. To better justify this, I read that OpenBSD removed loadable kernel modules in 5.7 release (2014), mainly for the same reason we do - nobody used it so they had no good reason to maintain it. Still, OpenBSD had LKMs being effectively working, which is not the current state in our project for a long time. An arguably better approach to minimize the Kernel image size is to allow dropping drivers and features while compiling a new image.
