Tow pilot got slow on climbout, brand new DG300 stalled on tow below 150ft AGL, glider released and hard landing destroyed the glider.

Totally goofy, but plausible.

Now, I'll anticipate the next goofy scenario which is glider release failure.
Let's not carry all of this too far.

Totally goofy, but implausible. We need to draw a line somewhere. I take your point.

The guy that would fail to promptly pull the release when his glider stalled on tow would be the guy who was surprised to suddenly learn that it was possible to stall a glider on tow at 60 knots, and that guy was the tug pilot in Bill T's anecdote. Best to learn these lessons on the ground.
