And if someone wants to modify the image with the same degree of
freedom (...same range of options) that's the version they'd need.

Netflix users download ~2GB/hour to watch a movie.

How do *they* share them?

Remember that the GPL allows you to charge costs to deliver the source
"on a durable physical medium". So if it would take two dozen hard
disks to send me the source, that's what I would have to pay for.

A source requirement isn't going to be added, but it's not as
outlandish for professional/semi-professional production as it might seem.
