The alternative scenario is equally plausible:

Sysadmin is trying to install software manually, lacks expertise in configuring. Eventually\
the sysadmin attempts install from rpm packages, mis-configuration is overwritten,
and everything Just Work. Which isn't true if the newly installed configuration is
renamed with a .rpmnew suffix.

Enough already: you know well how RPM behaves with %confoig, and you are
able to patch in whatever behevaior you choose: I told you how to patch
in the behavior you desire.

You do realize that RPM5 embeds libgit2 sufficiently well to perform
a commit that git(1) understands? Discusssing Newer! Better! Bestest!
%config handling, with (.rpmnew/.rpmorig/.rpmsave) handling is
so so so last century ...
