See, and this is why regular quoting is preferred.
Anyway, I kinda gave up You claim that I'm wrong when I say something isn't currently possible, only to add that it could be made possible. So how exactly was I wrong there?
And why would it be always wrong to state that some things are best added as mods or extensions? If Mojang followed that line of thinking I guess we never would have gotten customized advancements, functions and the upcoming recipes. Unless you can back up that claim with facts I can only pick that up as an opinion. And as you said yourself: opinions don't necessarily invalidate things.
See: as the previous poster also mentioned some of your suggestions would gobble up a LOT of extra resources. Having lived the dramatic 1.8 start it's something I really don't fancy of seeing happening again. So if a suggestion would actually dramatically add up to the required resources while it only caters to a smaller amount of players then yes: I think in those situations it would be a much better idea to fill those in as a mod. Because that way players get to chose themselves as to what they want or don't want to play with. But also because this will also prevent the game from becoming too resource hungry. There are already plenty of players who don't use the full maximized graphical settings because it would be too hard on their computer. Adding even more demanding things would only make that even harder.
