The NTSB recommendations do not appear to have addressed the sole and only cause for the Hudson incident. That is bird ingestion at the most crucial and common phase of flight, take off.
Perhaps the only item that seems to whisper some clue to the real issue is quoted below from the report as follows.

Compelled by the ever increasing need for profit by airlines, aircraft powered by two engines with thrust equivalent to three or more engines is demanded from engine manufacturers. This can only be achieved by increasing intake and fan sizes. The resultant larger area contributes to increased risk for bird ingestion.
Now, the question is how could this be resolved.
