Bjorn,
Springdale is alive and well. Version 8.2 was just made default 3
days ago. From my usage so far, it's been working smoothly.
I use netinstall and an Ethernet cable for personal and one-off
installs. It can be loaded onto pretty much any USB stick to not
waste a CD/DVD. At work, I run a mirror for campus installs and I
boot clients to the network via PXE. Network installs are very
quick with a local mirror.
It seems you are looking for the full DVD image, which we support
as a "would-be-nice" feature. It is a curated image-local
repository with some additional boot params. We don't often use
this in house, and we rarely have time to build a "would-be-nice"
feature otherwise.
None of this is to discourage anyone from building the Springdale
DVD ISO in collaboration, all the resources are available.
