I was once on the other side of this. A nice guy wrote a whole ton of code for a module, refactored things to the max, made it "testable" and a bunch of other things. He was very nice, very enthusiastic, and really wanted to help.

But I had to say no because it didn't fit well within the overall project, and didn't really add any value but a lot of complexity. I felt very bad to turn him down but otherwise I'd be now responsible for code I have no interest in and code I don't feel helps users.

The right way is to talk to the maintainer and agree on what to do first. Or be prepared to run a fork.
