What to do with the "Created by" header comments?

In a port I recently submitted, I included the "# Created by: ..." line 
at the top of the Makefile I had seen in other ports.  When the port was 
committed, that line was excluded.

Should I strip this line from ports I maintain as I update them, or let 
it sit until a committer does a tree-wide removal?
