Yeah, quite possible. I haven't worked on the project in ~six years and lost all context, but I'd revisit it and see if perhaps there was a simple solution if any of it was still current.
While core.async pays homage to go, it's simply not go, and it's harder to work with, and generally the changes are going to be more invasive, and looking around at modern resources, I don't see anything that indicates much has changed. So while I might have been more efficient if I'd had the go mental model, that was definitely not the only problem. Migrating was too much to do in my fairly large project, hunting and pecking at each instance I made an async call. Whereas with F# it was truly mechanical and hard to mess up, as I described above.
