Typically each channel takes its own course and evolves at different speeds with different needs. Trying to engineer a common set of APIs that serve all channels eventually leads to ever increasing FE logic with a backend API with leaky abstraction (by virtue of trying to accommodate different UI concerns).

By decoupling the BFF APIs which are geared towards a UI specifically, in a way you are moving a big part of the logic and orchestration to the backend and keeping the UI layer super lite. From practical experience, this has been a very helpful pattern both in my startups and enterprise career.
