User blog comment:P進大好きbot/Summary on historical background of BMS/@comment-30869823-20180713171021/@comment-37411086-20181111232111

Well, in terms of promising a powerful function but not being completely well-defined it would make the Bashicu Matrix system a lot like Bower's BEAF.

However, people benefited when they tried to make extensions of BEAF that were actually well-defined, and it encouraged people to try their own hand out at making a notation. (There are a lot of blog posts extending BEAF in the early history of this site.) So it would have been better had BMS been well-defined, but since it isn't I think we should make the best of it and try to make it well-defined anyway because then people can learn something by trying it out for themselves. It won't hurt, anyway.
