I'm just a lowly Zamus secondary, Lucario is my main, but I would argue that these pseudocombos should actually be given credit. No, I have not attempted to play ZSS on a higher level of play and I do agree that many of the "combos" mentioned are easily DI-able or AD-able, but just because they aren't perfect frame traps like many of Lucario's strings doesn't necessarily mean that they aren't useful.
For example, if your opponent is not a pro who is highly familiar with all of Zamus' attacks, you may be able to pull of a Dthrow>Uair early in the match. Then later, when they realize that they can AD to avoid it, use Fair to delay and hit them with the second kick. Who needs frame traps when you have mind games
Also, I'm not sure if this was previously mentioned but I've had amazing success with an opponent at low percents by following an Uair with UpB and then using another Uair.
