Maybe i missinterpreted your conclusion, but this what I get in one of my packages:
 desktop-mimetype-without-update-call /usr/share/applications/...

Now that we have triggers, I really don't see the benefit of adding such a
lintian warning. Imho we should get rid of dh_icon and dh_desktop completely and
also any manual update-desktop-database calls, not recommend to add such a call
(to potentially a *lot* of packages).

Why should we update dozens if not hundreds of packages, if we can have the same
effect much more elegantly and efficiently with file triggers.

FWIW, I'd recommend to update desktop-file-utils (update-desktop-database),
shared-mime-info (update-mime-database) and libgtk2.0-bin (update-icon-caches),
to provide proper triggers support and as soon as that has happened even reverse
the lintian check, i.e. if it finds any dh_icons / dh_desktop /
update-desktop-database call, issue a warning with the recommendation to remove it.
