> They don't really have any massive gaps waiting to be filled. Except the Standard Model is at best incomplete, at worst flawed, considering for instance galaxy rotation discrepancy (i.e. a need for dark matter possibly super-symmetrical, or modified formulas etc). Obviously black hole physics, expansion of space... There are many open questions, hard problems still unsolved. There's even a nice wiki article about "unsolved problems in physics". However I very much appreciate your point and think it's something to keep in mind when building models.
