City Governors & Intelligent Agents

I build 20 factories in a row, and follow every single one with a coal power plant. When the 21st factory is built, does the governor suggest a power plant? No.

I'm going bananas! I've been at war for 50 years now, with three different civs. I am building Tanks, Bombers, Carriers and Battleships. Every time a coastal city is done, it starts building a Privateer. What am I going to do with a Privateer when the world's oceans are ruled by Battleships? I have never built a Privateer, not in the current game anyway, and it's nearing the end of the 20th century. When will my Governors learn that I'm not interested in Privateers?

Actually, I have an idea. It's quite simple. How about being able to obsolete, or at least temporarily disable, older units from production? I wonder why Swordsmen and Longbowmen are still options when I have Infantrymen, Artillery and Tanks rolling off the production lines.
