CORS and wildcards.

One of the conclusions of
http://www.veracode.com/blog/2013/03/security-headers-on-the-top-1000000-websites-march-2013-report/(which
is worth reading) is that developers often misuse
the 'Access-Control-Allow-Origin' header. At a glance, about 0.5% of the
sites that use the header send invalid values, mostly wildcarded like
'http://*.domain.com'.

Is there value in paving this cowpath?
