This not gonna work on most servers anyway as even open source ones have restrictions so you can collect only nearby boxes. So on most servers what you could achieve is only the collection of nearby boxes just like you could in old DO times
If server allows behaviour presented in the linked video, I am wondering what else it allows. Probably all kind of bugs are there
Also, from the server side it is trivial to add additional restriction where you can literally collect only box very close to you which in effect would block bulk autocollection even for nearby boxes.
