You're rejecting this person without giving them a chance. "You're wrong" "You did something bad" "You have the wrong mindset". There is no room to be correct. There is no room for a bilateral implementation of a feature. There is no room for a collaboration mindset.

I only rejected his out-of-the-blue implementation of something that already had very different plans around it. There is room for whoever doesn't disregard what the readme says:

"For code contributions, it's best to start out with modestly sized fixes and features and work your way up. There are so many different possible implementations of more major features – many of which would cause undesirable code or vision conflicts with OpenMW – that those should be talked over in advance with the existing developers before effort is spent on them."
