>sometimes proposed changes that increase the engine's strength are rejected because they're too much code

that seems insane.

I know, doesn't it? But sometimes someone finds a way to simplify the patch so it's less code and almost as effective, and sometimes future improvements are made easier because the existing code is easier to work with. And it's hard to argue with the results.

Insane in the short term. But in the long term, if they make the program less maintainable, they may prevent future improvements.
