Is it safe to say that countries that really depend on tourism (like Greece. AFAIK they were open weeks before the rest of the EU) will never re-implement restrictions no matter what the EU recommends?

I'm flying to Austria on Friday and I do not want to change my flights across the pond. I got J for an absolute steal and I know I'll never be able to change the dates without paying thousands of dollars extra. If Austria bans Americans, I'll just book VIE-ATH for a few hours after my IAD-VIE flight arrives.
