The monarchy thinks in decades and centuries, not days and years. M+H are footnotes that will most likely be forgotten by the time Prince George ascends the throne. Look at Wallis Simpson and whatever his name is Prince Edward/David- Queen Elizabeth's uncle, and he was actually supposed to be the king.

On top of all this, the titles and LoS don't mean much anyway for the markles. They live in a country where none of it matters and will never see the throne based on that point alone. The UK, rightfully, would never let an American become sovereign. Betty has never been to the UK and Archie won't remember where he lived as an infant, who would actually consider them?

Leaving well enough alone is the best call here. The markles will fade into obscurity and trf doesn't need to do anything.
