Is warmonger gameplay well developed in civ 7?

I've been watching streams and overviews but I can't seem to get a sense of this. I love me some warmongering and domination victories—how does that play with the new age system?

Also one of the streams I watched the game ended with Operation Ivy, which took just about as long as building a few nukes, so does that mean the era of nuclear warfare will be pretty short? (i.e. you are racing opponents to Ivy unless everyone just agrees not to.) Heck for that matter, is domination in the modern age basically go Ivy or go broke?

Would be great to hear other warmongers' thoughts as compared to civ 5, or 6 (I didn't play 4 enough to comment on it.)
