Fine, let's call evlog "an enhanced printk" and discuss the specific technical
details of the proposition.

Whenever you change/enhance such things you may need coexistance for a while.
However this is configurable, and to a certain extent temporary, bloat.

Actually this is pushing the formatting out of the kernel, is more efficient,
and it leaves more flexibility to the logging daemon!
