I get why forest, stronghold and halloween maps are removed because they may not have been so popular but hijacked was a beloved map and I believe it should be brought back. It is visible from spawn so it should be easy to get it added back. I know many people including myself who had this as one of the favorite maps and it will bring back fond memories.
Neutral. It'll be super OP just to camp in the corners in the water. Will support once they fix bedrock not causing damage.
