When the "boot" parameter refers to a non-existent device, the only visible output at normal log levels was a rather confusing: ERROR: There's no '/dev' on rootfs. That's because the actual error, not being able to find the root device, was only a debug message, which gets ignored in the default mode. Promoting the "root '$bootparam_root' doesn't exist." message from "debug" to "msg" gives sufficient context to understand the error. A more intrusive change would be to change also the control flow.
