OK, well, all I will add is that I've been where you are on this now, and I've also been an architecture astronaut, and now I'm somewhere in the middle. This is where I've landed based on long experience. I know which code I prefer to maintain, and it's not the big ball of mud that, in my experience, inevitably results from insufficiently abstracted designs. I'm absolutely not making my life harder; I'm making life much easier for my future self, and this is borne out by actual experience on projects I've worked on. However as I said, there's no hard and fast rules, so, you do you.
