A NetBSD posted a blog stating NetBSD is having issues porting Wayland due to Linux specific items. OpenBSD stated something similar.
Both articles indicated it will be a very long time, if ever, to get Wayland fully working on their systems. I did see this presentation that describes some issues as of 2025.
Why would they do that? When I started learning VIM more than 20 years ago, one of the main reason was that it (or vi) was already present and installed in every possible Linux system.
