Yes. It is a bit of a nostalgia trip, but it also has practical
implications for users of older computers with only CD drives. They will
have to find a workaround. I know that Canonical anguished over this. It
has been the subject of much discussion for years and they have spent lots
of time in past years paring down the ISO by cutting things out. Now they
have room to grow for years to come.

I think there is still a net install or minimal CD (for now). But for that
you likely need a wired connection and broadband. Some people will no doubt
get left behind. There are plenty of distributions that will work for them,
but few are newbie friendly, unfortunately.
