Dive routes and trainers broke up the pace(ORAS even added ace trainers surfing on pokemon and diving trainers for extra variety) and gave you an almost completely different set of pokemon you could encounter. The same could be said of the abandoned ship and the current puzzle west of pacifidlog.
The game also doesn't really make you traverse it more than once or twice(not including going back for missed collectibles where your mileage may vary). I'll take this over Rock Tunnel or Kalos Route 13 easily. I do feel a little bad for how it screws over some pokemon you get just before Lilycove like Rhyhorn, Vulpix, and Phanpy, though.
