Hi Pedro, I don't support this removal.
Currently, yes, the flag doesn't do anything, and it's unlikely to do so in future, as Nikita points out.
However, it's not improbable that we might see a `u` flag in future, and if that was added, `b` might still be useful as an explicit counterpart.
Anyway, this feels like deprecation for its own sake. As you point out, removing this breaks widely-deployed code. When the benefit of removal is negligible, and it breaks existing code, I don't think it can be justified.
