I used to be of that mindset (re: become a republic) but tbh I'm more of the line of thinking, if it ain't broke... With the parliamentary style of government, you need a figurehead. So you'd have to tear up a whole host of UK conventions going back centuries and re-jig everything, just so someone else gets the ceremonial role?

Much as some might like a complete re-write, I say expand the unit tests around it if minor bugs arise ( e.g. https://www.bbc.co.uk/news/uk-15492607 ) and let the system run unless a major blocker comes up ;)

King! King! No point in the thing!
