Sergey Beryozkin commented on CXF-7070:

Sure, some headers can be considered sensitive - however completely filtering 
them out will lose the log record of what the the actual Authorization/etc 
values were. For example, if it is OAuth2 Bearer token which is either 
encrypted or is a simple DB pointer then dropping it completely from the log 
record is not ideal, similarly to the case where the logs are pushed to the 
secure file system/etc. 
If losing the log records of such values is what is actually needed then it has 
to be done optionally IMHO (ex, if a given message or bus property is set).
