> Note that OCaml 5.0 focuses on minimal (solid) support for the multicore runtime system, and will not provide stable user-facing concurrency and parallelism libraries.
Progress + report on OCaml multicore has been exceptionally well done for many months [0]? Quite big piece of work, impressive to see it materialising as general public availablity. I wouldn't be worried about higher level abstrations at this stage. Well done runtime part is the most important now.
Wouldn't hold my breath
