are pacifiers really that bad?

Today is the first day I gave my son a pacifier. He has been either cluster feeding or simply needing to suckle the past few days and I just wanted to run to the store without taking my boobs out along the way. Of course he got upset on the ride so I decided to use it. But now I feel bad. Everyone says it'll mess up my supply bc his suckling/cluster feeding helps to boost production. Or he'll become dependent on it.
