IMHO it would be handy to aid debugging efforts by enabling the dyndbg feature provisioned by kernel [1].
Though not sure what is entails in regards to cost of storage a/o CPU a/o memory it likely could benefit the development of the distro by being able to generate more in-depth information on user nodes for potential mishaps.
Dynamic debug is designed to allow you to dynamically enable/disable kernel code to obtain additional kernel information.
Currently the CONFIG_DYNAMIC_DEBUG
kernel config flag is unset.
