By that logic if it doesn't exist and someone sends a patch, I should simply
ignore a review comment about that patch breaking some non-existent ABI and
simply take it.

Well, it certainly works for me.

Unless you folks come-a-runnin' later screaming it broke some use case of
yours. And then we're back to what I've been preaching on this thread from the
very beginning: having a common agreement on what ABI Linux enforces.
