I wonder why the Gas Station is so good for sponsoring transactions, yet not many projects use it. Does anyone know the reason?

The Gas Station is indeed a fantastic tool for sponsoring transactions because it reduces friction and improves user experience by covering gas fees. However, its adoption may be limited due to the complexity of implementation, lack of awareness among developers, or the additional costs that projects might incur. Increasing education and providing simpler integration tools could help boost its usage.
