I figured they would be relatively minor things, but I was curious just the same. XD

Why do the credits need to be reconstructed?

Special Edition credits are not the original theatrical credits as they have somewhat different font, spacing, coloring, timing, and, of course, extra credits squeezed in for all the Special Edition work. To have an all-around proper original theatrical recreation/restoration, the credits would either have to be reconstructed from scratch or scanned and cleaned from the original film reels (well, to have it in HD, anyway). And really anything about this project that you might wonder "why would he have to do this or that" is likely answerable with "so it can be a proper theatrical recreation/restoration". Anything less is not well received around these parts...
