Hookless for road bikes is a dead end manufacturing fad that only exists to increase manufacturers' margins. It does not provide any aerodynamic benefit. The weights are not substantially different. The low tire pressure maximums are not suited for road tires. The manufacturing cost savings are not passed on to consumers. Hookless might improve strength in a way that matters when tires are flat or otherwise bottom out (i.e., maybe useful for MTB, where the pressure maximums are not a concern). Hooked wheels are moving wider, too, of course. 21mm internal is now relatively common and you also see 22-24mm internal road wheels.
