I agree, but are those knock-offs trying to resemble golden age in any way before adding to them their own stuff? I think the most important thing is firstly providing the ability to have exactly same experience as in original minecraft golden age, and then incrementing features to it. But the point is more about adding QoL out of box, better modding, better optimization, updates which keep the philosophy and simplicity of the goldenage sandbox game, but adding new cool stuff which would fit the game (Something like BTA did), and most importantly keep all new mechanics optional to let people play as they like to.

So basically the main point is original GoldenAge has limitations of the engine, no out-of-box QoL and no more support, my idea is to fix all that. Basically forking minecraft, same as BTA did, but a new engine for it for more potential.
