I wonder if there is a sequence of loader commands and/or configuration (both at kernel compile and at boot) that can assure the kernel mounts the root filesystem installed into itself?

Yes, if it gets to the point of "can't find init" it has already
successfully mounted the root filesystem (although, perhaps, not
the *intended* root filesystem).
