The thought of a return to more of a hub-and-spoke model sounds like a total nightmare. It'd take a huge price difference before I'd consider that, personally (EDIT: As in, I usually check "direct flights only" or equivalent and only relent if the cost is ridiculously much higher). Then again my perspective is being near multiple large international airports, so maybe that might appeal to some.
Hub and spoke is primarily used to fill large planes. If you have 10-20 passenger electric planes you'd land at some random county airport, eat a hamburger or a taco while the plane recharges, then get back on the same plane and finish the trip. So you'd have a layover like hub and spoke but all the concerns about missing connections go away.
