Btw, mineclone2 also rebranded as Voxelibre, months ago, and for the same reasons.
Voxelibre now actively moves away from copying Minecraft exactly.
If you want the closest copy (and my personal recommendation) check out Mineclonia.
You can use the mod lib from contentdb. Also it is worth pointing out that they are moving towards a subgame focus not a mod focus. The original game has been discontinued and isn't preinstalled. You install a game like Asuna to get gameplay and content.
Of course you can still use Minetest game as a base for mods. I do that for simple worlds.
