I think this theory is wrong. (Unless dpkg keeps packages in
trigger-pending state *after* a successful apt-get upgrade.)

I tested earlier this week the following upgrade path in piuparts:
Upgrade from jessie task-gnome-desktop with --install-recommends to
stretch (but with desktop-file-utils and shared-mime-info switched to
interest-noawait triggers in stretch).
The first (apt-get upgrade) phase upgraded both of these packages as
well as gnome-menues and finished with success. I assume there are no
pending triggers left at this point, and the 3 interesting packages have
noawait triggers.
The second phase (apt-get dist-upgrade) still runs into the trigger cycle.
