IMHO, its relatively easy to get even trained people (except at rather high levels) to over extend.
So yes, I tend not to throw them but let them fall because of their own body momentum, mechanics, and alignment. Also because either their mind really wants to hit me or their mind really doesn't want to be hit by me.
Is this where the confusion lies with no touch throws? That the no touch throws are not actually throws but people using ukemi to get out of the way of being hit themselves?
