Quite the opposite, I imagine.
The rehearsals were for the coronation, something other European monarchies often handle by simply having the new king or queen sign a document in parliament, but which was considered necessary in the UK, even at a time of widespread poverty and inequality, chiefly to reconcile the public to the monarchy at a transitional time after a widely-respected queen died and a much less popular figure took the throne.
Chancy times for the monarchy, when there’s a transition from a safe pair of hands to a man whose life has been spent waiting for his mother to die, interfering in politics, marrying unsuitably, being a notorious adulterer, who then compounded his sins by marrying his affair partner, who is being crowned by his side, at a time when his brother is widely suspected of having sex with underaged trafficked girls, and his son has defected and gone public about his treatment by the RF.
Of course they needed rehearsals, the state coach, horses, soldiers, the Archbishop of Canterbury, pageantry etc!
I don’t think we should be congratulating people for showing up to rehearsals to ensure they retain their privilege.
If Edward VIII and Wallis Sampson and the death of Diana (and even Harry/Meghan) taught them anything, it’s ‘be careful who royals fall for/marry — it’s lethal if they’re too popular or too unpopular. And manage transitions carefully.
As regards the day to day ribbon-cutting and speeches, they just show up, wave and smile, and read a bland speech someone else wrote for a carefully-vetted, undivisive charity, surrounded by staff and security who arrange everything from transport, loo breaks, carrying tissues, make-up repairs, to who is in the curtsying lineup and presenting bouquets. There will be no hostile press questions, no requirement for an in-depth knowledge of the charity’s work, no requirement to be anything more than a body to be looked at while making the right noises.
