What should they do instead? You have to rush to patch in any case. If the maintainers start to label commits with "security patch" the logical step is that it doesn't require immediate action when the label is not there. Never mind that the bug might actually be exploitable but undiscovered by white hats.
If you do not want to rush to patch more than you have to, use a LTS kernel and know that updates matter and should be applied asap regardless of the reason for the patch.
