I can definitely see standardizing the format strings, at least
well enough that they can be parsed out and accumulated for
statistical purposes.
The bigger problem right now is KTR for 64-bit. We can't use
vaargs due to the massive overhead the 64-bit varargs code uses,
so we need to some up with a better KTR API, maybe one with different
macros each taking a different number of argumetns so we can
efficiently generate the KTR entries.
