No, I wouldn't. I have been working for years on the same codebase, it's not that hard to keep it clean and simple. I just refactor/redesign when necessary instead of adding hacky workarounds on top of hacky workarounds for years until the codebase is nothing but a collection of workarounds.

And most importantly I just design it well from the start, it's not that hard to do. At least for me.

Of course we all make mistake, there's bugs in my code too. I have made choices I regret. But not on the level that I'm talking about.
