I would also like to see if these updates in any way address Haller's comments about Brave back in 2016: https://portableapps.com/comment/229066#comment-229066 but another thread noted they have little interest in portability. So probably not.
On a related note, Brave has already been forked as "Disenter" (intentionally misspelled). I mention this only to say I'd avoid it. I found their license to be unclear and I wasn't impressed by the "comment anywhere" plugin, which I've seen in various forms over the years. Their current website is also real light on details. The problematic group behind it also doesn't appear to be a software company, so it's unlikely they'll really be moving forward with a strong browser effort.
