For the purpose to pass messages from early init through to final boot.
Systemd continued this for the same purpose. Which I agree is totally
legit. But where systemd fails, is that it continues to use this
interface far beyond the need.

I agree with Andrew, we should have had a way to close the pipe after
the system was up and running.
