Well, if it doesn't have a "Civinator-function," it should! - And, of course, TY for pointing me to that thread. It's a bit humbling, after being away for 3-1/2 years, to begin a mod, full of Grand Ideas,and realize how much I've forgotten, especially after I spent so many years testing and documenting this wonderfully crazy game.
I've also only just glanced at the first few entries in tom2050's thread, but this did leap out at me: "Destroying City Buildings - It seems Charm artillery pieces WILL NOT destroy a city building UNLESS a building with Charm Barrier is present in the city! Then it will destroy all other buildings 1st, and will destroy the Charm Barrier building last." I'd hoped (mis-remembered?) that a Charm attacker would target Charm defenders (like, City walls) first. It's a shame, especially given how many fine siege units are out there.
