I´m inclined to agree but there´s one thing about 5e rogues,as already said here: You can only make ONE sneak attack per turn.

So maybe you want to SA with your off-hand weapon or with your next attack (if you multiclass and have several attacks per turn or have action surge) so an automated SA would take away those tactical options, forcing you to SA an enemy maybe you do not want to:
Ej. you have an almost-dead distracted enemy nearby and a full-health shaman few meters away, threatened by one of your allies. You may want to use your first attack without SA to terminate the first one and then move and stab the shaman with a full SA damage using the distraction your companion provides.
