I am generally in favour of decoding as well as possible, though to
be honest that would include not failing for a missing reference but
instead using a black reference.
At the same time, we now have decode_error_flags we could use to signal
a (potential) error until the next keyframe while still decoding the
frames.
We might need to discuss how exactly to use it though...
