If there are built-in dependencies and any of them is built-in in the kernel, modprobe -r fails with modprobe: FATAL: Module module_name is builtin. It makes sense to ignore such dependencies for the case when removing is called for non-top level module. Example: cifs module, it declares bunch of softdeps and the first one fails on some kernel configs: modprobe: FATAL: Module gcm is builtin.
