I can speak only for me. I don't want to be an anachronism in some distant future. We're a very long way from cryo being a viable solution anyway. Bring a formerly healthy rat back, then we'll talk. :)

Consider how our current world would treat people from the 18th or 19th C. Would it be endless media titilation, Buzzfeed memes of 20 things you didn't know about Bob the Victorian? Would there be the discrimination akin to how we treat indigenous or third world peoples? Would we help Bob the Victorian to get fully up to speed with society, or just see a curiosity?

So, for now, I'm happy with my lot.
