I've worked with production Java systems for many years, and have had to tune GC, implement suballocation schemes etc. It is definitely not a panacea, and I meant to say that it was not, in my original comment. But at least GC fixes mostly leave the source code alone (ignoring suballocation tricks). I find reference counting to be less intuitive, and I don't like the fact that fixing reference counting problems require modifications to source more often. My Swift usage stopped in 4.x, so I'm unfamiliar with the 5.0 improvements.
