I recently wrote http://jdebp.info/FGA/original-vi.html and was thinking of doing something like this, to augment it; because Sven Guckes's list (https://guckes.net/vi/clones.html) is definitely dated and incomplete, nowadays.
It does not have #NeoVIM (for obvious reasons). Most lists of clones miss that there are several forks of Bostic #nvi, not least the two forks that are in #FreeBSD and #NetBSD base. Similarly, #DragonFlyBSD has forked nvi2.
