Question on USER in container

I have a question about the USER id that is being used in this container image, currently it is set as 1001. The upstream image just leaves the USER as root for the image. I understand not wanting to leave it that way and have the root user default in the container, but the similar ironbank base fluentd image uses different set instructions to create a fluent user and group that is used. And that pulls from the similar implementation from the upstream image maintained by fluentd.

There seems to be a couple of Github issues relating to non-root uses in this container 420 and 1357. Personally, I don't have the same requirements, I'd rather have the fluentd user/group inside the container, but before I make my own image, I wanted to reach out and see if this was something desirable to add here?
