No need! Even with dip1000, you can pass scope values to 
non-scope parameters in `@system` or `@trusted` functions:

```D
void f(char[] str) @safe; // parameter `str` is not marked `scope`

void g() @trusted // checking stack pointer lifetimes manually 
here
{
     char[32] str;
     f(str[]);
}
```

The scopeness of `str[]` ends then and there, no viral 
application of `scope` needed.
