EASA action
The AAIB report reminds us that "CS-25.80312 requires that all passengers and crew can be evacuated within 90 seconds." and that the EASA "...stated that emergency evacuations had also been captured as a candidate
safety issue within their safety risk portfolio for commercial air transport (fixed wing)...".
The AAIB Safety Recommendation to include carry-on luggage in the CS.25 timed evacuation will show that aircraft can no longer be evacuated in 90 seconds due to pax behaviour.
Let's hope the EASA are quick to act.
