Thank you...

I will bet that a program, starting with logging everything with free form text to the same ID would, if used by sysadmins, quickly be improved upon, in regards to id logging. As a sysadmin I often have to look through source code to find the real reason for an error message (that's one big reason I prefer Open Source) - and if the program already used something with support for proper logging, like journald idea - I would easily whip up a patch for upstream to improve logging for the instance - helping myself in the future as well.
