1. As long as he's called Louis XIX, they'll be happy. (And in my experience, royalists in post-royal countries normally think they have some claim to the bloodline. So they probably all hope Louis XIX will be them. I hope they give it to the 6'4" black chap with dreads and a giant wooden broadsword. He'd make a better leader than Manu. Fact.)
2. You really must think I'm thick as pigshît. I've got a first in history and have lived here on and off since the early '90s, yet you don't think I know why my fave streets (outside India) were built? Dear God. The point is that firstly, It never kicked off between 1851 and the Fr-Pr War. Because L-N III was, by the standards of the day, a very benign, progressive ruler. So I don't see the wide boulevards as a way of making sure the cavalry could charge the mob, I see a beautiful, liberal culture, that peacefully entrenched the 1848 settlement. Though I admit to having a bit too much of a soft spot for the 2nd Empire by lefty standards.
3, Yes it is. I'm right and you're wrong and that's fact. (Lutyens New Delhi is beautiful in its own way, but it's only for the elite and govt. I'm in a council flat on the right bank looking out the window at the river and Ile St Louis. And there are only 3 proper cities on the planet - London, Paris and Delhi. Oh, and Benares. Are you going for Benares as the most beautiful? I'd be hard pushed to argue that given it's Ganpati's mum and dad's city. Hhhhmm. Well done, B, there's hope for your soul yet.)
