I suspect Civ 7 needs a big gesture in order to take the narrative back. As it stands I'd maintain it's a great game, just one which most of its audience weren't asking for.
If I were firaxis I'd be looking at how to put Civ Switching on the chopping block. It's probably a lower hanging fruit to switch up than the era system, or other big bugbears. Removing something likw that would count as a big gesture toward one of the biggest causes of dissent.
Either that or they could try nerve stapling their audience...
Why negating us Mountains crossing and city settling on top of Mountains? You just need to add a few more Mountainous art terrains, with some flat tops, and humans anyway had always had the capabilities to shape any kind of terrain to their will. Most jewish settlements in Palestine were built on top of impossible places, for the best defence possible. The Romans built Mountains passes with huge Guard gates on mountainous terrains all over old Europe. Roads on mountains were essentials for them to travel around, and when Napoleonic France took over, they took possession of the ancient Romans gates to Italy and screwed Italians a long shot. To this day France still holds the most valuable defensive positions in the western Alps.
We've been asking this since civ III, because there were mods were you could settle cities on Mountains ( the notorious True Earth Map with Tibet ) and it was Epic. Ever since Civ IV they denied us this.
Why? I can understand you can't build a city on a Vulcano, but not a road. The Etna Vulcano is full of roads, and caves systems, small villages. It's just stupid.
Big gesture?

Map Editor
Release full Assets control for modders (maybe ask for credential, idk, but open up a bit)
Sea colonies - Sea transport vessels (No walk on the waters option) and all related rewriting of the land-sea transitioning (Scouts ok, Marines Ok, Berserkers OK, all others... nope)
Orbital Units and colonies
Seamless experience from 4000BC to 4000AD (With good Space colonization, and maybe 1st person dogfights---- got the idea?)
Ride your Horse in 1st person, or be the King, or Princess, in 1st person, make it like the Sim, where you can adorne your Palace, and Throne Room.
Now. Which one of these would you consider "Big concessions"?
