So, regarding the potential Steam release mentioned in this progress update, I decided to reach out to mystman12 about the possibility, and this was his response. So unfortunately, there will be no Steam release of BFNSU.
However, he did say fangames that don't use the Baldi's Basics IP (such as DFAC) are allowed, so that leaves the possibility open for Baldi's Basics fangames that I develop in the future that use original IP and assets to be released on Steam.
