What are the potential pitfalls of changing the layout in phpbb2?

Changing the layout in phpbb2 can potentially lead to compatibility issues with existing plugins and themes, as they may not be designed to work with the new layout. It is important to thoroughly test the new layout to ensure that all functionality remains intact. Additionally, updating the layout may require modifying core phpbb2 files, which can make future updates more difficult.
