So I expect this to no longer be present; basically cloud-init has changed

This output should still be there though, and that's what we should focus
on figuring out. The serial-getty service running on sclp_line0 is what is
_supposed_ to be producing this output.
I guess you should try this on an LPAR install where you can actually get
into the system: can you post the output of systemctl
status serial-getty@sclp_line0.service? And maybe systemctl
show serial-getty@sclp_line0.service? TIA
