I don't think it's necessarily bad. In fact it is quite an elegant solution to issues between frontend and backend teams. I just think it's a great example of Conway's law. Conway's law (IMO) was never a negative thing, merely an observation of the realities of software development.
Your post brings up an interesting angle which is that the frontend and backend people can have different expectations of what the backend should actually do (perhaps leading to dependency spaghetti). In this case, introducing a BFF can be a way to isolate that from the rest of the architecture.
