9: fragment scrolling

Section 9 says:

   CSS UAs in visual media must, when scrolling a page to a fragment identifier,
   align the top of the viewport with the target element's top border edge.

Isn't that wording a little over-constraining?

For example, what if a user agent wants to show the user some context by
scrolling the identified fragment to slightly below the top of the viewport in
order to show a little of the content before the identified fragment.  If the
UA still showed the user the location of the identifier fragment (e.g., by
rendering in the left UI border an arrow that pointed to the location within
the viewport of the identified fragment), wouldn't that satisfy the intent?
