What are "relative line numbers" in Emacs?  I see nothing in these
discussions that describes how (with what commands/packages) the line
numbers were produced in Emacs.  So it's hard to tell anything
intelligent about this issue.

The right place and way to discuss this is by filing a bug report with
all the specifics, including a recipe for reproducing the issue,
preferably starting from "emacs -Q".

Thanks in advance.
