What do you think is the hypothetical limit of what most Taylor Swift fans would uncritically accept?

Clearly Taylor Swift is at a level of stardom where she could totally release an album in a genre or style that's completely unexpected and weird and her fans would mostly be on board with it, but I still think it would have to be within some kind of limits. There would have to be some amount of abrasiveness or weirdness in the music where the fans would think it's bad and/or a cry for help instead of good. What are those limits? For example I think power metal Taylor would probably go over totally fine, but thrash metal Taylor would be over the line and she'd lose the audience.
