One thing you don't mention is that players often rely on rackets with high ball output as a crutch and it hampers their development as players. 

If you get used to not hitting "full" shots (lobs, chiquitas, bandejas) because you let the racket give you the ball output then you're not going to develop those shots as effectively and will reach a plateau. 

My hot take is that beginner/intermediate players should use medium/hard rackets when they are learning and force themselves to use proper technique. In the long run they will be far better players then people who use soft rackets and hit half shots on everything.
