The issue is the dynamic libraries (which are handled by distributions in different ways). Try statically compiling a binary like that and you'll find that it will work between distributions and kernel versions.

Because they include their dynamic libraries with their programs, which has its own tradeoffs (updating security issues in shared libraries is much harder, even if you had a package manager on windows -- which you don't).

Right, but GP's point was that Linux doesn't have userland-to-kernel stability and I was saying that's simply not true. It's true that there is no stable upstream driver API but there are also solutions to that problem as well.
