Is having this as a test criteria *that* burdensome? Similar to another blocker that was being proposed, maybe it's not something that _must_ be tested, but if it's known to be broken that it should block a final. Maybe I'm missing something, but unless the image is over the capacity of a DVD, what would prevent the success of an installation?

Well, since I did forget about them and it has been 15 years (3X your upper end
estimate) I don't think they are that important.  I'll
check them again in another 15 years.  If I have a DVD drive at that time.  :-)
