I have yet to hear anyone in over a decade make the case as to removal of the movement you cite that would have any beneficial upsides.
It might seem odd and abnormal and difficult to understand, but in actual use it has no significant negative effect, as long as we are not talking damage from say an accident, etc.
The only time the "slop" enters the picture is when backing up, or wheel is off the ground and if moving, in a vacuum, or the wheel magically is in motion with zero drag/friction.
