I would not take solace in IPCC retiring a scenario. Their predictions are based on conservative aggregates of existing science, and have always been considered by many in the climate science community to be underestimating climate change.

This is exactly wrong as it relates to RCP 8.5. A number of research papers came out basically showing how 8.5 was completely implausible, and it was only after these papers were widely cited and reached consensus did the IPCC retire 8.5.

This article by some of the original authors of one of those papers explains the situation well: https://www.theclimatebrink.com/p/on-the-death-of-rcp85 . If you actually read their linked research paper, I don't think any unbiased observer could think 8.5 is plausible anymore (and, in fairness, 8.5 was always proposed as a worst case scenario, not a "business as usual scenario", as that climatebrink article explains very well).
