I read that interview, but there are other parts of the game that are clearly incomplete and need to be added later. I don't see that it is conclusive that they will not fix the action requirements. Consider the rough state of many other basic features like dual-wielding, long/short rests, and status effects, how they are also still experimenting with the game, i.e. initiative grouping. It could mean they will alter the mechanic later.
Shove and dash are clearly defined in 5E and have requirements based on attributes and actions. I would be surprised if they just ignored all of this in the final version. Giving free auto-succeed abilities out of class eliminates class identity and unbalances the game, so I hope they read these threads.
