9 years down the line, people are still believing the blurbs on the WWW that in fact pre-date systemd-consoled. Whilst Kmscon itself still exists, having spent the time from roughly when David Hermann (now Rheinsberg) pulled it from systemd until 2025 under the stewardship of Peifeng Yu, there's no sign yet that people who make distributions are building Linux as a general rule with the in-kernel terminal emulator cut out.
Would that they were! I, for one, first proposed this in 2006.
