I like to tone down my buttons if they are in disabled states with bg-opacity-* opacity is not preferable as this will also tone down the text. Lets say my buttons have no multiple types like primary, secondary, success etc. with the new way i would need to explode my logic for applying the disabled state for each type instead of just adding the bg-opacity. would you say this is a legitimate Use Case for introducing this utility back or am i missing another feature of tailwind?
