We seem to be discussing arguments why something should not be backported, rather than arguments why something should be backported. You seem to be saying that the barrier of entry to stable is lower than what we'd normally send to Linus for an -rc, which perhaps makes sense in other parts of the kernel, but in networking that doesn't compute. We go by simple logic of deciding if something is a fix. This is not a fix. Neither is this: https://lore.kernel.org/all/20250604005049.4147522-54-sashal@kernel.org/
