There was quite a debate about the Queen attending or not back in 1991. The King virtually insisted on her attending, which some parlamentarians were not too happy about at the time, which I find odd because it is the origin job of every female or male consort to support the head of state at events such as these. I couldn´t think of any other monarchy which would have discussed this. And Queen Maud also attended when she was not abroad and could somehow make it.
So, no, this is not just about tradition.
