Problematic, no. It can be easily implemented.

But it's an option we discarded. It makes no sense to log to both 
destinations. If you're using a tool that can read the syslog, then it doesn't 
matter which one it was sent to, but it will be a problem if you send to both. 
If you're using a tool that can't, then you want to send to stderr only.

If you have legacy, set to 1.
