Effectively reverting parts ofd314d47, this commit removes the new functions that got added to remove the flags parameter. Instead, it just marks the parameter as unused and documents this. Having what is effectively an API break just to remove a parameter is a bit overkill. The other parts ofd314d47which cleaned up the usage of the flags parameter are untouched here.
