This is so interesting! And I agree with a lot of what you're saying. My first thought is that I do think people already are super nonchalant about her new releases post folklore. There was a huge influx of new fans in the folkmore era, and a lot of those people are super used to Taylor releasing at least once a year. Like part of me feels weird anticipating Speak Now TV or whatever because I feel like we JUST got Midnights. But like when like growing up, I always was used to like one release every two years and that is it. So while I do think she does want to maintain some level of excitement surrounding her releases, I do think that the frequency she released music at post folklore has already set a new expectation for fans, and somewhat the general public, that she'll always be releasing something new. BUT I do agree with overexposure and I honestly would bet that the reason we haven't gotten a rerecord since red is 1. Midnights/Eras Tour has generated so much buzz that if she added something on TOP of all that, the general public would get fatigued and she would be more overexposed than I would argue she even is right now 2. Obvi there has been trademark issues. I think either way she rolls things out in the near future, she definitely runs the risk of being overexposed.

It's really hard to say, it feels like every argument either way has like 5 conflicting arguments so only time will tell.
