Short post on the Phoronix site .... (https://www.phoronix.com/scan.php?page=news_item&px=Debian-GR-Closer-Init-Diversity)
That wiki link toward the end of the article is now in the forbidden category; apparently the options will be:
Choice 1: Affirm Init Diversity
Choice 2: systemd but we Support Exploring Alternatives
Choice 3: Focus on systemd for Init System and Other Facilities
So that looks like Debian will still prefer Systemd over the other init systems rather than treat them all equally.
After scaring away all those who did not like systemd, I am not surprised they did not majority vote to affirm init diversity. So much so, I'm not even bothering to check to confirm that's how it went, such is the strength of my presumption.
