Reverting it now was certainly a pile of work, but that's neither here nor there for the portion of the story bothering people. It's like they threw rocks threw the windows years ago to make them slightly clearer to see through and now put a ton of work in to undo that because they discovered that made no sense in reality.

It's great they did all the work to fix it after the fact, but that doesn't justify why it was worth throwing rocks through the window in the first place (which is different than not doing optimizations).
