If done right, rethrowing exceptions does not affect the ability to debug the code. You don't throw a pristine new exception on the spot. You wrap the exception in a new one, effectively maintaining all the information. Coded recoverability suffers, but debugging ability does not. You have the same debugging information in the rethrown exception as you did in the bubbled up one.
