I believe that's already the behaviour that falls out of the current implementation <https://searchfox.org/llvm/rev/1f0b8ba47ab0f1dc678099d4830d0cc0d10850b6/clang/include/clang/AST/RecursiveASTVisitor.h#2809>:

  DEF_TRAVERSE_STMT(CoawaitExpr, {
    if (!getDerived().shouldVisitImplicitCode()) {
      TRY_TO_TRAVERSE_OR_ENQUEUE_STMT(S->getOperand());
      ShouldVisitChildren = false;
    }
  })

If we are not visiting implicit code, we only visit the operand, otherwise we visit all subexpressions.
