What tripped me is that in `applyPatternsAndFoldGreedily` this PR explicitly sets it to `true`:
```c++
  config.fold = true;
  return applyPatternsGreedily(region, patterns, config, changed);
}
```

@jpienaar could you add a tl;dr section to the PR description that lists the API-level changes and suggests how to integrate this in downstream projects? The motivation is very clear, but what to do with the PR not necesserily.
