Let me take two examples,
FE10RE, after you open it with FEB, you can’t see the materials such as battle animes, etc. Guess why? Is it because the author’s level is too poor, which leads to a bug, or is it because they actively avoided FEB recognition?
Another example, such an battle animation, have you found it in the public F2E repo? No, because it is not open sourced. However, such a material is indeed under development. The original author stated that the project will not continue to develop until they find the effective way to prevent thieves dump them through FEB.
¯_(ツ)_/¯
