I think we did not tell him to go away. It was just that the patch itself
has some downsides in that it can break existing howtos (that do contain
console=tty0).

We could revisit the initial patch (I think we also need to change
arch/s390/kernel/setup.c set_preferred_console) and then
we would need to test all possible combinations on LPAR, KVM, z/VM
and see if we could fixup existing documentation.

Would Valentin be willing to provide a new version that also touches
setup.c?

Or, as an alternative we could revisit Valentins initial patch for the
installer.
