Agreed; however, the normal usage of the expectations file handles this fine (this is how Chromium uses it): use one expectations file for all of the QT ports. Results that are the same across all subports need no modifiers; results that vary can have them, e.g.:

BUGWK12345 : foo/bar.html = TEXT
BUGWK12346 LINUX : foo/bar.html = IMAGE

indicates that all of the Qt ports fail the first but only Qt-Linux fails the second.

The complication arises if you want to also share expectations with a different port (Gtk, Apple, Chromium, whatever), in which case you'd have to add some way to distinguish qt-linux from chromium-linux, or if you want to have expectations that are common across *all* ports, e.g., because every port will fail the test.
