Yes, if a user explicitly specifies something like "earlycon" on the commandline then not automatically getting console output on tty0 is fine AFAICT. The use case important for me / distros is when no console= (or related) arguments are present on the cmdline at all, then the desired behavior is to have console output on tty0 as well as on any serial console specified with stdout-path.
