Cool that you're into retrocomputing, but many of the rest of us think perhaps some features added to vim from the last 30 years might be useful.

That vi was standardized was one of the many failures of POSIX as an idea. The very idea that we should freeze a text editor for all time is silliness in the extreme.

While you may be a detractor, Apple appears to be an ardent admirer.

Yet they ship macOS with vim installed and zsh as the default shell.

Don't let on that OpenBSD does not have vi either. Its vi is actually nvi, yet another vi clone, that Keith Bostic derived from elvis.
