FD,
As I recall (EASA land) reverse is not considered at destination in dispatch calculations. However, … wait for it … operational requirements may change due to the application of ‘TALPA’ performance as required by Certification Specification CS-25 Amendment 27 (change info, retrospective application, at page 14 onwards -(https://www.easa.europa.eu/downloads/134260/en).

This suggests that dispatch to a contaminated runway can use reverse where approved by new calculations for contaminated surfaces. Additionally to a wet runway classified as ‘Slippery Wet’ (code 3) n.b. previously / same as Slippery When Wet as in NOTAMs. Note potential confusion with with Boeing / FAA terminology involving slippery runways.
FAA position uncertain; new ‘TALPA’ contaminated performance data should be applied ( as 25.1592/92 ), but a get out of … via AC 25-32
