Yeah, I don't think it's all that bad, and they have already done a bit of streamlining. For many things, what I end up doing is just setting a crafting building, let's say a bakery, to produce a certain item indefinitely. For example, I can have several bakeries which are just producing bread, which then supply all my cities with that as an amenity. At that point, they don't really require any attention.
I feel like I should be careful both understating and overstating the issue. I suggest looking at more gameplay as it becomes available, and try to make a decision for yourself as to whether you think the crafting would become too much to manage. I personally feel like it mostly falls somewhere between enjoyable and tolerable, but I am still hoping for some improvements to the UI (which may already be there at launch, since they have received the feedback a while ago), and maybe some further streamlining.
I do like the idea of crafting in general. If we take food as an example, say you don't have the most fertile terrain, but you have a bit of coastline, and some fish resources. You can then produce refined products like salted fish, and "import" it as an amenity in your inland cities in order to support them. I love stuff you like that.
