How about ,since baby piglins are safe to approach, the player can befriend them by giving him some gold or some food when he seems to be hungry and is obviously abandoned for whatever reason by its peers . This should be rare as we don't want to be this common for "bullied" baby piglins. And when they eventually grow up they will never attack you! They will Wait by the nether portal for you to return and in order to increase the chances of him staying loyal to you,you would have to build a house near the portal for your nether friend! You could do this with the nether spawn block that should be added in the near future. This is gonna be a great and wholesome addition to Minecraft and learn to treat a kind soul in need with love and respect.
And as a reward it would throw you some partly valuable items like the cat when you wake up. For example there would be a 0,04% chance of it giving you a wither skull. Thank you for reading this!
