I wonder, could they not create a single test email exercising all 58 features? Then one would just have to open the test email in a given client and compare it to a reference rendering. (Kind of like the Acid1/2/3 tests of yore.)

I would guess that there are certain unforeseen interactions between failed implementations, maybe certain ones prevent emails from being rendered etc. I suppose those could be documented as well, but would take a lot of extra effort to figure out the combinations.
I'm guessing the feature list has grown over time. Each time more features are added, 58 clients need to be checked.
