My understanding is that if you indicate that a roadway is dedicated for public roadway and utility purposes, you aren't stating that said dedication has been accepted by the public agency; that is completed by a certificate or statement of acceptance before the dedication is finalized.
Often I've seen this reflected in statements on Subdivision maps by the City Council (or equivalent) stating that they approve the map and all parcels dedicated for the public use thereon.
Since I would expect to have such a statement on the map, any statement which denotes an area for dedication as public Right-of-Way shouldn't need to quibble over "offered for dedication" or "dedicated".
I'm sure I can find some good examples given a bit of time. I have one in particular in mind that I referenced the other day, if I can get a chance to find it.
