The diff is changing the way that augmentedValue() works.
It's removing a call to value(), which was previously being called on an object returned by augmentedValue().
This change will affect all code in this project that calls $content->augmentedValue('seo'). In particular, it may cause errors if any of those places were expecting the return value from augmentedValue() to be an array instead of an object (which would have been true before).
I'm not sure what other effects this might have because I don't know how else or where else '$content' gets used throughout the rest of the application and whether there are any assumptions about its type elsewhere in our codebase; however, since we're using PHP 7 now, we should probably just remove these types altogether so they can be inferred automatically at runtime anyway...
