There's a very interesting mechanism design idea—incorporating quote commitments in ongoing transactions into the trading volume statistics. What does this change? Users often feel that exiting a trade is a "waste of effort," but from a different perspective, if each interaction counts, then exiting itself becomes a complete part of the trade cycle. This reversal of incentive structure can significantly improve market engagement and liquidity. When trading is no longer a one-way "in and out" process but is quantified as an equal contribution to the market, the overall activity and stickiness of the ecosystem will be greatly enhanced. Such detailed design elements often determine the long-term competitiveness of a platform.
