When using mods that change how biomes look, such as "Alien Biomes", it would be nice if this mod took that into account and regenerated the land according to those.
I can understand it can't cover every single biome-changing mod out there, but at least the big/popular ones. (such as "Alien Biomes")

I tested the mod with alien biomes on 1.1.21 and it seems to work ok at least on an initial quick and dirty test. However I cannot account for edge cases - it really does depend on how the individual mod authors did their extensions to the world generation - especially ones that use multiple surfaces, there's just too many different ways it can be done. Besides, with Factorio being "done", in theory map generation is now stable and there should be less need for this mod going forward (other than resurrecting old maps as was the original use-case for this)
