Yes, and with Full-round, standard, move, free swift, immediate, and miscellaneous actions, all of which everyone technically got, but could only use some of, the action economy of 3e was pretty complicated and confusing! It wasn't a laudable aspect of the system.
Thus, the change - you can move and get an action. Those are the only things you know you get. You *may* get a reaction. You *may* get a bonus action. But the latter two are not guaranteed.
Your quibbling over what it "really" is is quibbling to return to more confusing language. It isn't simplifying the matter.
