The point for the contributor is that, yes. The point that would convince the Linux kernel maintainers to actually accept the patchset, though, would likely be the introduction of generally-useful "species of sync primitives." In such a way that those primitives can be used to solve the "hard part" of WINE's virtualization of NT's versions of those primitives; but which wouldn't be constrained to guarantee an efficient zero-impedance call path between those implementations.
