As documented in 20.x, we'd like to keep reduced BMI off by default for 1~2 versions. And now we're in 22.x. I rarely receive bug reports for reduced BMI. I am not sure about the reason. Maybe not a lot of people are using it. Or it is really stable enough. And also, we've been enabling the reduced BMI internally for roughly half a year. So I think it's the time to move on. See the document changes for other information.
