The last time I tried the game, it worked on Intel driver, which means it uses OpenGL <=3.0. Right? But AMD driver supports OpenGL 4.4 (I don't know about Nvidia driver). So why don't you develop the game without restrictions and add an option, which'd be disabled by default, to use OpenGL 4.0+ in functions and shaders?
What does this have to do with freedom of development?

I think you use OpenGL <=3 to make it work on Linux without AMD or Nvidia drivers. You'll be more free, if you can use the latest supported OpenGL version. 
Wouldn't it be "more free" to allow more people's drivers to work?

You can make option to enable modern OpenGL. People, who use Mesa, won't have some effects and will have lower performance.
The baseline for OpenGL is going to be whatever the current Mesa version supports. It doesn't make sense to support two separate renderers, especially when a significant number of our players run Mesa.
You're suggesting to double the amount of work for renderer programmers. Such wow, much freedom

This seems the only disadvantage.
