Re: CFC: Target Size and Target Size (no exception) SC

Another option for an exception to address Gregg's concern could be

- the target in part on a group of more than 10 navigation elements

The rationale being that if there are less than 10 links in the group there
is not much good ui rationale for squishing links together... but when
there are a lot of links then the user without a disability is being
punished by the space because they have to scroll and links are not in view
