You are not providing any justification why the prefix is not
wanted. Just saying 'We do not want' does not cut it and who is 'We'. I
certainly not.

I really disagree because the prefixes are very useful for searching log
files. So not having it makes it harder to filter out for no reason.

Thanks,
