If you are serious about improving your game, this should be avoided. The higher game settings (AI bonuses and cost reductions) exist because the AI is pretty bad at managing its worker turns. So even at Regent where you are 'equal' to the AI, you are actually much further ahead. Why would you want to give up your greatest advantage against the AI?
IMO, the single greatest investment to early game improvement is worker management. I actually prefer to move my workers, but I am a buildaholic. I love to improve tiles. I never, NEVER automate my workers. The way I think of it is that I wouldn't automate my armies because the AI is so bad at fighting wars. Why would I trust the AI to build my industrial base any more?
Same goes for Governors. You can win while using the Govenors. But they don't micromanage so you get the same, poor AI results.
