Well .. I wouldn't expect (for #1 and #2) to happen right away. I'm not that naive.

... but it will need to happen eventually. I am just saying those things will need to happen if they expect significantly more people in the parks

There are just some people that won't go back until things are at least more "normal" (to them personally).
And by relaxing restrictions .. I don't mean like dropping them cold turkey. It definitely is a double-edged sword .. some people are staying away because of the restrictions .. some people are confident and coming because of the restrictions.
Disney will probably loosen some restrictions and just not advertise it. Like allowing more reservations, like putting another party in a small world boat or allowing more seating inside the restaurants. But they WILL advertise certain things coming back like M&Gs or Fireworks that will probably encourage a lot of people to consider coming again.
