BulletML was developed by ABA Games (aka kenta cho, creator of the classic rrootage, which is now open source). It was rrootage that sent me down a rabbit hole and eventually stumbled onto fal-works and firedancer after someone suggested their works had the same aesthetic appeal. The libbulletml c++ library is still somewhat used in some niche vertical shmup games (mostly Japanese indie games). You can read a little about bulletml and the history of it all in the libbulletml readme file.
