Generally I don't see much reason to try and mod the game in its current state, before Sardines is even finished with it in a real sense. This is a different situation from, say, Karryn's Prison, where the base systems were baked in from the very start pretty much, so the pregmod made sense, with Elulu it seems like Sardines might even be looking to rip the "combat" system out of the game for the violence edition altogether, turning it into more of a sandboxy VN than anything. Trying to maintain most mods in that context would either mean remaking most of it, or creating an entire new branch of development for the game.

Most likely,
Melody Memory, as pretty much the only person directly in contact with Sardines. Not that it truly matters, as it was bound to be discovered sooner or later (if not on ulmf, then somewhere else (like arca guys, for example)) regardless.
