Fumble beyond the LOS

Technically you should always bag a fumble spot because there might be an inadvertent whistle. Having said that, if the fumble is behind the LOS then it probably doesn't matter much because the team last in possession at the time of the IW would have a choice of taking the results of the play (i.e., where the fumble occurred) or replaying. Can't think of a situation where the fumbling team would want to take the results of the play (if it ended behind the LOS).
Just seems to me that it's good practice to bag the spot of a fumble, regardless of the location.
