QuickTime is purely (for everything that matters) userland. Some
hardware usable from QuickTime has kernel extensions (FireWire iSight
comes to mind), but outside of that there are no large kernel
dependencies. If QuickTime had hardware decoding support, things may
be different. In addition, QuickTime doesn't depend on recent userland
frameworks, e.g. less stable APIs. The File Manager hasn't changed
much in years past, targeted additions like FSObjectCopy
notwithstanding.
