It'll work... until it doesn't, especially at his drip per second flow rate. A steady trickle is recommended to help keep pipes from freezing but even then a deep cold snap can still freeze them up.

I thought it was more about providing pressure relief for when they do freeze, like in this This Old House clip: https://www.youtube.com/watch?v=AuPO5hKdo8A

That too, if you're thawing pipes you absolutely want to open the faucets as they thaw out, especially if you're using a heat gun/hair dryer to thaw them out.

That's the opposite of what the video showed, it shows the pressure rise from the pipes freezing.
