They'll never stop in-person meetings (too much loss of control, thus while they will continue to sell some KHs, many will still be needed (so no. 2 won't happen). That also means 3 & 4 won't happen, at least not on the scale you wish for.
5. Nope. Not happening. Too valuable a tool to keep the drones hamster-wheeling
6. Nope. Not in a million billion quadrillion years. Fear of DFing is the primary weapon to keep control
7. Sounds like a wish list of things you'd like to see happen, but which won't happen
That said, I could - maybe - MAYBE - see them eliminate one in-person meeting per week. I.e., the "midweek meeting" remains as a zoom item, while weekend meetings are always at the KH. But even that I'd rate at less than 50% chance of happening. Other than that, back to "normal" as soon as practicable. Imaginative and creative these guys ain't.
