  The Reported-by tag gives credit to people who find bugs and report
  them and it hopefully inspires them to help us again in the
  future. The tag is intended for bugs; please do not use it to credit
  feature requests. The tag should be followed by a Closes: tag
  pointing to the report, unless the report is not available on the
  web.

If you believe this is out of date, please submit a patch with new
text to this document.

I find it valuable being a person. It indicate somebody is bothered by
the problem you are fixing. We see a lot theoretical bug fixes, which
in practice nobody ever hit. I would prefer to spend my time reviewing
real issues, not theoretical issues, and the Reported-by: is a quick
indicator of this.

After reading this document, did you spot the second issues?
