I'm not a fan of the slimmed down monarchy trend going on.
While I do support the idea that only a limited number of royals benefit from public funds (the 'working' royals), the concept of actively reducing the number of princes/princesses who hold titles can easily and organically reduce itself over time.
Long gone are the days when monarchs had several children, who went on to also have several children. With most couples now only having 2 or 3 children, and some of them being daughters who won't pass on their titles to their own children, there will never be dozens of princes/princesses running around in any one country like there used to be.
I fear that the slimming down trend, sometimes done with blunt force cruelty (see Denmark) and gradually eliminating all the pomp and circumstance that has traditionally surrounded the monarchy, might just plunge it all into irrelevancy if it gets too modernized. Monarchists, at heart, like the fanfare surrounding their royals.
To quote Mr. Carson from Downton Abbey "Where's the show?"
Of course, by keeping the current LPs in place you will get the Harry & Meghans occasionally, but you get the Edward & Sophies too, and what would the current King Charles do without them?
