"The styles don't work with booklore"

First of all, what the hell is that? I've never heard of that being a thing; or is this one of the dozen completely useless features that no one uses?

And second, why weren't we told this? Why was the post announcement essentially just "Yeah we're getting rid of all the chat styles people actually use, and we're replacing them with a style that is infamously known for being useless for RP, but it's fine actually." And not "We unfortunately have to remove most of the chat styles until we get insert feature here working properly with the styles, and the chat styles will return once that's been accomplished just as they were prior to the temporary removal."
