Thanks for this, it is a good explanation. Something that the article itself missed, for obvious reasons I’m guessing.
I would hope the Queen or someone in England would make a statement on this, but I may be holding my breath for nothing.
Unfortunately it would be inappropriate for Her Majesty to comment in this case, both by convention and constitutionally. She is no longer Queen of Trinidad and Tobago - they became a Republic in 1976 - and it would extremely inappropriate for her to interfere in what is an internal matter under their Constitutional law. It would be roughly akin to her coming out criticising the United States for not allowing prayer in schools. It's not her place to do that. It's an independent sovereign nation, not one of her dominions.
But there are more subtle ways in which her views can be made known. When Canada decided to stop using Imperial Honours, Her Majesty was happy to create a new Order of Canada in her capacity as Fount of Honour. When Australia made the same decision, the Order of Australia was created under the Crown. Ditto for New Zealand.
She has made no such offer to create a new Honour for Trinidad and Tobago. If they don't want the one she created in 1969, that is their affair - but they can create their own replacement which has no connection at all to the long history of British Chivalry.
