Oh, here's the one.

One concern I have is that whether Zed changes its defaults, this won't be updated — ideally we want to go over every PLAIN_TEXT config usage and ensure a value from the editor settings is taken.

I noticed this wasn't pulling from the default settings which is why I didn't initially find it. I don't quite understand what you're saying, but would love to pair on it at some point in the future.
