That is not true. lavf returns an error code, that is exactly what it is
supposed to do. The application is then free to handle the error code
however it needs, including reconfiguring the decoder to bypass the error by
using a catch-all encoding.
Your proposal removes the error code, this is just plain wrong (bis).

"Return an error code" and "crash and burn" are not the same thing.

A text editor is not a library. For what it is worth, my text editor
occasionally refuses to save files because of encoding problems that I need
to resolve manually. This is the only reasonable behaviour.
