Thanks.  Sounds fine to me, but I'm not familiar with this part of Gnus,
so I can only offer a couple of nitpicks.

The commit message conventions followed by Emacs are described in the
file CONTRIBUTE and also under (info "(emacs) Format of ChangeLog").
It's fine to include the free-standing prose, but the commit message
should also mention the file and definition being changed, e.g.:

* lisp/gnus/gnus-icalendar.el
(gnus-icalendar-event--build-reply-event-body): Display a warning
instead of barfing when user is missing from attendee list.

Why not 'gnus-icalendar instead?
