I disagree. I think it's profoundly liberating. As liberating as eliminating AD&D race-class restrictions and eliminating AD&D human dual classing vs demihuman multiclassing. I think it's more liberating that eliminating pre-5e class alignment restrictions, more liberating that eliminating AD&D racial level maximums, and more liberating than eliminating 1e AD&D gender strength limitations.
I agree that some of what each race or subrace gets doesn't really reinforce what the game says each subrace's culture values. The game has historically used racial ability modifiers as a crutch for accomplishing that, and it really shows if you eliminate how they pigeonhole (i.e., stereotype) each race. However, that doesn't mean racial ability modifiers are actually a good design, just that that design has an impact on play. I agree that, for example, mountain Dwarves seem to benefit non-martial classes much more, but I'm not convinced that it really matters that Dwarven Wizards prefer to wear breastplate or half plate.
