You shouldn't have much problem with it. You'll run lower pressure in front and have a nicer hand feel. Just remember, when your at the limit your front will have more traction as it is bigger. Usually you would want that anyway.
Mine was in the context of my 650b gravel wheels, in case that wasn't obvious. For road, I use 38mm slicks front/back, but maybe I should put in a larger tire in the front. At some point, toe overlap becomes an issue.
But 28 front, which is what you were asking about, should be fine. (I can get 28mm front/rear on a 1980s bike.)
