They still can. If it required headcanon before, it still requires headcanon now. What is making it more difficult, if you can eventually evolve into a modern America regardless? The explicit codification of prior Ages isn't jiving with what you considered to be the proto-name you evolved from?
I get not liking the more out there switches, but that's not something you have to engage with.
When I start a game as Greece, with the civilization-specific great people, civics, wonders, districts--I am firmly playing as "Greece." I am not really thinking about my eventual evolution into America, Mexico, Britain, etc. The change into Normans or Spain isn't as smooth or subtle than what I was describing previously. It's a sudden, choppy, and violent change. It's a fade to black without a credible explanation and a confusing rebirth. Yes, I have the option to employ a few policy cards that give me extra % influence on diplomatic actions, but where has Greece gone? Where are my little great writings that my all of my little Logios created? And the game's answer to that is basically: don't worry your little head about that -- better start colonizing -- here are your Greek policy cards and a conquistador! Would you like to found Buddhism in 1000 AD? Better study Trade (again) and re-learn the concept of currency! And if I'm Greek into Spanish Catherine the Great then why am I speaking Russian? There's just a lot of wacky little layers that strain immersion (for me) more than past games.
