I was shooting for making you _think_ exactly about what you wrote in the above paragraph, i.e. what the current logic does and if it is sensible, is overly pessimistic for some files, and/or is risky for some other files and if so in what way, as that would help you record the thinking behind the different treatment for files based on various file extentions clearly in the log message.
