Under this framework, Rust's async fns would not be colored, since any function in the callstack could be blocking on an executor. if you consider "spawn point" a part of the callstack, many other languages are similar.
This doesn't feel like a useful distinction, but i don't think "function coloring" in general is a useful framework.
