Here is a question/ challenge... How would you like to see the British flag changed? I agree with you about the inclusion of Wales on the standard. All States are equally represented... Commonwealths are not.... Puerto Rico, and the Northern Mariana Islands.
Even the Union Jack has evolved the past 200 years to include Northern Ireland and the St. Patrick Cross. While Wales has had a much longer union with the British it does not get represented on the Standard. I also believe that one day the six northern counties are returned back to where they belong and that aspect of the flag will be removed. That is my opinion and not a matter of discussion.
