"Will I be accepted as a guest when I fall in love with a place online? Will the host cancel the booking a couple of days later because his aunt visits and he needs the apartment for her? Will be there when I arrive at the venue? Will everything look as promised by the pictures on the platform?"
– That moments of uncertainty and adventure are fine if you are travelling on a budget. But if you are willing to spend 200 Dollars or more per night, you don't want do deal with such stuff.
Does it make sense?
Sure, on first sight it makes total sense to expand the range of Airbnb places into the premium segment where certainty & safety from unwanted surprises is a must. More options are always better.
What will change?
That certainty could turn out to be expensive for guests though: If I had to guess, it would be that Plus places will mostly not be new apartments but venues that already performed very well in the past (and did not cancel, no-show or negatively surprise you otherwise). How else would would they have the reviews & ratings making them eligible for the Plus category in the first place? So probably nothing will change with this hosts and places but their prices: they will definitely go up.
