Interesting!  I literally tell folks all the time that their changelogs
*should* tell a story. :)

I think this is clearly a case where you and I have differing personal
opinions on style.  I understand what you are asking for, and this is
usually a case where our friendly maintainers can help out of they have
a strong preference either way.

This is my personal opinion, but I think this interpretation takes the
documentation a bit too literally.  The documentation speaking about
"imperative mood" applies specifically to the language about your fix,
it does not apply to the background.

It is there to encourage contributors to avoid some of the more passive
language like:

	This patch does blah....  This patch fixes blah...
