Recently Sarah Gooding reported some good news at the WordPress Tavern about the upcoming Twenty Twenty default WordPress theme to be released in WordPress 5.3 in a post called Anders Norén To Design Twenty Twenty Default Theme Shipping In WordPress 5.3.
This is great news, Anders Norén has made some good free themes that I would be using today if they had some of the newer features and some options that I need in a theme, and so I am more hopeful that he will make a usable default WordPress theme.
