Well, the config file format is older and fileConfig() does not cover as much as dictConfig() does. (For example, filters). I don't propose to spend time enhancing fileConfig(), now that dictConfig() is available. If you are forced to use fileConfig(), you can subclass the handler for those projects where you need custom terminators. This is not much work, and you can use that subclass on all projects where you need custom terminators.

What I proposed was not a workaround, exactly - it's how dictConfig() is *meant* to be used. The reason for supporting factories for handlers is that users can set them up however they want.

I closed the issue because I showed that no change to the stdlib was needed to provide the functionality requested, and as I got no response about it from you, I decided to close the issue. Sometimes, people see a solution proposed which addresses their problem, but don't close the issue themselves.

So, I would like to close this issue, because I have proposed a way you can do what you need without the need to add anything to the stdlib. If you feel the need to reopen the issue, please do so, but give me a good reason why the approach I suggested doesn't work for you.
