I did alliance with AI, sent a couple of trade routes (AI did the same) and I ended having 50+ resource of every type (having 1-10 before this alliance). This completely breaks "strategic" part about those resource - since they are basically unlimited once you form an alliance. There is now no need to capture/fight for specific territory to gain more resources.
I think the main problem is that resources via trade route are created out of thin air. If you had like 1 Floatstone, and your partner also have 1 Floatstone, then you can create 10 trade routes between your cities, each giving you and your ally +3 float stone (6 in total) per trade route, increasing resource availability by xx times more than what is available on map.
Hope they fix it. Previous system where you could trade them for other strategic resources (or for energy/science/cities/peace/war) was much better.
Also: units that utilize strategic resources should be much better (either by strength, production cost or both) than normal units. You can pretty much win a war without any strategic resources against opponent who has lots of them. Currently I only get strategic resources for wonders and satellites. I never had a situation where it was like "oh, I need to capture this resource before starting a war".
