Your concepts are better and riskier than the base game. By riskier, I mean bolder.

Try switching from OpenGL to Vulkan or vice versa. 

It's no big deal, honestly. I wouldn't take it too much to heart. I was once very passionate about making 0 A.D. into XYZ, but over the years realized no one shares my vision. lol Now, I only develop 0 A.D. out of spite. j/k. But anyway, the engine itself is slowly evolving to allow for more and more interesting things, even if the base game doesn't showcase them. Mods can and will take up the mantle as long as the capability is there. 

I never wanted to create any conflict. I want collaboration: I want the gameplay people to help me, and I want the experts to help me too. But I can't handle the conflict.  I don't have the energy for it.  I want this game to be the AAA of open source. But I want us to do it together.
