It is such a long boring process to breed cows/mooshrooms, sheep, pigs, cats, dogs and rabbits so why not let the villagers do it. Obviously, the player will have to tame the wolves and cats but once those are tamed the villagers could take over and do the breeding then the player can kill/egg the entity.
I did post it on Mojang's facebook page But knowing how unique and special EMC is I thought this might be a possibility
So the shepherd, my concern is that this will push updates like 1.13.2 (which is already held back enough), and eventually 1.14 back even farther, which disadvantages emc from other servers.
1.14 will overhaul villagers and make them considerably more complex, which will probably make it harder to code this in.
To be entirely honest, I do not think this would actually be difficult to implement, or even keep up to date. You are not really altering the behavior of anything, more just adding a new behavior that requires some certain conditions, like if(villager==farmer){ find all the mobs; If(chest next to villager has wheat or whatever in it){ feed the mob (aka mate or what have you) } } even with wild changes to the underlying function of villagers, these are easy things to implement/update. HOWEVER, the real question is, SHOULD you do it. I feel something like the above is just going to make a player lazy rather than actually improve any quality of life. So much of Vanilla Minecraft can already be automated with the systems in place, I can't possibly see someone as obviously anti-automation as Aikar implementing an INTENTIONAL AFK production element. Now... if Mojang added something to the like, then obviously its inclusion to EMC is nearly guaranteed, but asking the team here to implement something so... 'cheaty' before officially introduced is probably a bark up the wrong tree. But its important to know that the difficulty of adding something is not always (and most of the time in general) the driving force of whether or not a feature/request should be added. Vanilla Minecraft (with the EMC Sprinkles) is a well-balanced machine, and tipping the scale with something like this (however small it may feel) can really change large portions of the game and economy and rarely for the better.
