I don't think you have to go as far as Earthdawn.
Per the 4e D&D PHB (p 54):
Encounter powers produce more powerful, more dramatic effects than at-will powers. If you're a martial character, they are exploits that you've practiced extensively but can pull off only once in a while. . . .Daily powers are the most powerful effects you can produce, and using one takes a significant toll on your physical and mental resources. If you're a martial character, you're reaching into your deepest reserves of energy to pull of an amazing exploit. . . .Martial powers are not magic in the traditional sense, though some martial powers stand well beyond the capabilities of ordinary mortals. Martial characters use their own strength and willpower to vanquish their enemies. Training and dedication replace arcane formulas and prayers . . .
Limited-used abilities correspond to effort and willpower that are limited resources for even the greatest hero.
If that's all that's required to make something non-meta (as per the discussion of Force Points) then these abilities are not meta!
That doesn't help, because the people involved in complaints don't see why that would apply to individual powers. They'd probably have been more accepting of an "effort point" system or the like (and yeah, some of the complaints go way back to any "X a day" power for the same reasons.
Remember, a lot of objections to this are launched at gamism, so...
