On dry runways the effect of REV is not taken into account for PERF calculations. The scenario you fear is (all need to apply at the same time)
- wet runway or worse
- ASDA limited take-off
- RTO at V+-10 to V1

The chances are very remote. For what is left, the standard walk around check of REV lock-out pins should cover. No need to envisage new procedures where at least 50% compliance with the present ones would do. Agreed?

although from the report: https://www.atsb.gov.au/media/577576...-064_final.pdf
it is not clear whether the standard pin as seen here https://www.atsb.gov.au/media/577576...-064_final.pdf was visible on the outside of the casing.

Now, the paragraph "AMM specific wording of HMU deactivated ..." of the report is the funny part.
