Regarding 3 it has had coroutines built into the language since the last 10~15 years, much before the language Go made it more mainstream. preemptive threads is more recent. It does have a stop the world garbage collector, which is not good for concurrent applications, but the semantics allows one to avoid creating garbage to a large extent. Libraries is chicken and egg, one needs higher level of adoption to drive this. 5 could be a legitimate concern, but I dont think its going to be any worse than Scala or C++ in this respect.
As far as language design goes, Skaller the author is a well regarded PL theorist active on LTU.
I am not saying this the best, end all language, but one that has enough interesting features that would be interest to the early-adopter rich crowd that we have here. It certainly has grabbed my eye balls

I think you meant parallelism there. Felix does have preemptive threads for that, but its a relatively new addition, so I expected it to be rough on the edges.
You will probably be able to catch Skaller on LTU, ATS mailing list and of course on Felix's own mailing list. He can answer questions better than I can.
I think you will have to debug the generated C++ because I dont think it preserves the corresponding Felix source lines by default.
The good thing is that it supports functional style (though not restricted to it), so you can debug individual functions easily enough. Besides it has robust and flexible type system (way better than C++'s) that you can enlist to catch errors early. It does type deduction so you dont have to litter the code with types.
