This is a great development and should even be applied in other parts of the of the world. There is no point for people forced to liquidate their crypto holdings simply because they needed some cash and they are not interested in selling at the moment. At the moment, I believe the amount interest would be high which is understandable due to the inherent risk is what is being used as a collateral but eventually when the volatility embedded in crypto is minimised, this would become something so common in every part of the world.
