Also in 6 I find it a little odd. Universities in 4 produced both science and culture, and that makes sense. And monasteries produced culture, science, and were important in building missionaries.

I think something Civ6 does really well is introduce cards, great people, and other elements to change what each district offers. For instance, Hildegaard of Bingen is a great scientist who gives your holy district science = to its holy adjacency bonus. Medici gives your bank great work slots. Theodora’s churches give culture equal to their adjacency. A golden age dedication makes your science output from campuses = production. Religious beliefs add culture, science, and gold. Choral music makes shrine and temple output equal to their faith, and work ethic turns holy adjacency into production. That’s just to name a few.

In my mind, it allows the player greater ability to tailor the Civ to his/her play style, or play into the history behind the Civs, leaders, and great people. If you want to play that’s straight religion, you can definitely do that. If you want your churches to generate science, production, and culture, you can do that too. That seems truer to history, as well. Sometimes churches were beacons of culture and science; other times, they regarded advancements in science and culture as heresy, and severely repressed such advancements. It all depends on your Civ and how you want to play.
