For instance, `parallel` uses the implicit default data-sharing attribute, while `critical` just uses what's coming from the outer scope.

OpenMP 4.5, subclause 2.15.1.1 lists the rules of implicit data-sharing attributes. In fact, some of them are missing in Flang, like that of `task`: https://github.com/llvm/llvm-project/issues/64480
