What Hacker News says
6 sourcesAnd FreeBSD and OpenBSD supply nvi as their vi.
In contrast, there are plenty of people that push this as a handy default. It's all over the place and sneaks in via all sorts of routes -- very unfortunately for those people who want vi to invoke something that is closer to genuine Joy vi than VIM and NeoVIM are, even in their "compatible" modes.
Just one example is the default yashrc that is used by the Watanabe shell: https://github.com/magicant/yash/blob/trunk/share/initializa...
(Yes, this is the default, in the absence of a yashrc file, not the sample yashrc file.)
In No_colorFWIW yash is an impressive and mature project that seems to overlap with the goals of mrsh:
https://yash.osdn.jp/index.html.en
Yash, yet another shell, is a POSIX-compliant command line shell written in C99 (ISO/IEC 9899:1999). Yash is intended to be the most POSIX-compliant shell in the world while supporting features for daily interactive and scripting use.
I've installed the Ubuntu package and poked around at it a bit. Its source code seems well-written, and it even contains its own line editing library (i.e. the functionality of GNU readline).
It looks like it's still being developed, and magicant is the original author: https://github.com/magicant/yash
I mentioned it here (and just added a proper link): https://github.com/oilshell/oil/wiki/ExternalResources
I wrote some notes about POSIX here: http://www.oilshell.org/blog/2018/01/2
