One danger I can see coming up is that if someone writes incorrect code it could end up propagating throughout other codebases. I guess this is still an issue without automatic tools, but I feel like this might make it easier…

Aroma would only surface what it thinks is "idiomatic" coding patterns. So if you have many instances of incorrect code, you might already be in trouble :)

Given how many "everybody does X wrong" articles we see here, I think we're already in trouble. :P

(Thinking specifically of the "binary search in the Java API was broken for X decades" one with the integer overflow.)

If you discover a better pattern, it might be easier to convert across the application if the same pattern is followed everywhere. So you might consider this a win.
