Just some input from me, the nether and end were accessible before, but it was vanilla with no plots. Players made nether portals and end portals to enter the other dimensions purely to muck around with its resources, and this lead to access being disabled.
I did make a suggestion a while ago that if nether and end access is to be reinstated, that they should also be given plots.
- The plots would be proportional to the overworld plots (ie. 1/8 size), so that players automatically receive the nether and end plot corresponding to the overworld plot they claim.
- The nether plot should include both a ceiling and a floor of bedrock, and be separated by walls or netherrack rather than quartz paths. It should also have a ready-made portal so that players who are making a portal in the overworld automatically link to the right nether plot.
- The end plot should include only a small island of bedrock, and be surrounded by floating pathways of endstone/glass. Falling into the void merely teleports you to the central end plot where spawn is. Making an end portal in the overworld should send players to the corresponding end plot if possible.
