Because it's not clear to me that we won't want the same behavior that CSP
has.

That is, if I get two headers:

```
Clear-Site-Data: *
Clear-Site-Data: includeSubdomains
```

the current spec will combine them. I'm not sure that's the correct
behavior, and I'd like to make it easy to change our minds before shipping
the feature.
