The blog posts are warnings about what not to do. People, naturally, when they don't fully understand something or can't grasp the complexity of something want to rebuild. Because writing also helps us understand that is what we are building. But its a trap, what you've rewritten will never be the same as before and there lies the footguns.

The blogs are plainly stating, "even though you feel you should rewrite, you probably shouldn't."

Or some of us have experienced failed rewrites. It can be a potentially expensive mistake.
