BFF can live on a different stack from the heavier backend, and bear a different development cycle.
I've worked in a few orgs where backend devs work on both the standard backend and the BFF, often adjusting both when adding new features. It's just convenient to have a separate layer closer to the frontend, dedicated to it.
