Seconded. It's not enough of a saving /and/ reduces the value of having
the ringbuffer in the first place if data you want is never there.
There's a lot of noise to deal with - arguably that could be reduced,
but that's not something to be solved in Fedora directly.

Personally, I think kernel config is one of the last places to cleanup
after regular apps are taken care of.
