My opinions are that creating new snapshot archives to support
installation of testing snapshots is redundant/unnecessary, and that
snapshotting testing doesn't actually solve any of the core problems
in the CUT manifesto.

That's simply a technical limitation of the existing snapshot.d.o.
6.5 terabytes isn't that insanely large nowadays, and the size of the
current testing archives is probably more like 500 gigabytes. Hard
drives of that size only cost around $50 nowadays, but getting a 2
terabyte drive for $200 instead wouldn't be a bad idea/investment.
Ultimately snapshot.d.o can be mirrored, it just currently isn't. That
can certainly be fixed.

Why would you want to do this? The snapshot should be chosen because
it is in a good shape, not because certain packages have been forced in
without going through standard testing processes.

Why is bringing all of the latest features necessarily a requirement?
And where is that stated? It's certainly not in the manifesto.
Advanced users can get around installer limitations anyway. Taking your
brtfs issue as an example, once the user has the new kernel, they can
boot into single user mode, unmount the root partition, and use
"btrfs-convert" on their partition.
