The shift into offering these perks for on-site Resort guests will greatly impact how some people vacation. Whether guests move off-property or they choose an on-site Resort (Deluxe or otherwise). The only ones that may not be impacted directly are DVC owners, renters, and individuals who fork over the full price of the Deluxe Resorts + Villas. This makes DVC all the more appealing, which tracks with Disney's desire to flip Grand Floridian and build DVC-exclusive resort hotels (Reflections pending).
Those that stay at non-qualifying hotels will now have to look to Disney After Hours, Early Morning Magic, or any new separate-ticketed event to have extra hours in a park with potentially lower wait times (and "extras"–food, shows, cavalcades, etc). Those who wouldn't likely buy these separate-ticketed events prior to 2020 now may find them more appealing. They may be willing to pay an extra $400 total for an After Hours event for their family in one lump sum as it is significantly less that the cost of a Deluxe Resort/Villa that would, essentially, provide a "similar" experience.
It seems Disney is truly zoning in on shifting into a pay-to-play model (moreso than years prior), but is balancing the "value" for the dollar. And I haven't even touched on FastPass+, but my guess is Deluxe/Deluxe Villas will gain more perks as time goes on. (And on-site guests will also be provided some, but not to the extent of the higher-priced resort hotel guests.)
