Obviously, thirty years ago the amount of cabin baggage hadn't reached the ridiculous quantities now seen as normal on some flights.
However, the report doesn't mention carry-on bags, nor of any evacuation delays caused by passengers with such. Of the total 31 Safety Recommendations (page 171 onwards) it is clear that amongst other things, the seat-pitch at overwing exits definitely was a factor. It's perhaps noteworthy that having remedied that with more "generous" emergency-exit spacing, airlines now sell those seats to higher-bidding fare payers - obviously providing they're fit and able!
