It basically makes using larger flying machines impossible, and gives the technical Minecraft community one more reason not to update to 1.13.
Mojang, really, you should fix the game breaking bugs/mechanics, not implement new game breaking mechanics. It's so annoying that you do so many unnecessary upsetting, things, like removing of dragon egg bedrock breaking, tnt duping, and now flying machines are broken too. Why dont you add Movable tile entities?? All Minecraft players would be happy with this. It would be a replacement for tnt duping, and it would bring endless new possibilities. And don't say it's hard to implement. There are plenty of more that do exactly this. And it's not even buggy. When one single person, that doesn't even get payed for his work can do this, why the duck cannot a whole specialized team of full time coders make this happen? Fix your game mojang
McEndu I don't get your question, but I updated the description so maybe that answers it.
