Yes, I posted a fast-zero branch for all four projects that I touched
(with the obvious similar URLs). They might have non-fast-forward
changes as I rebase things (for example, the nbdkit stuff needs to
s/1.13.9/1.15.0/ in docs about which version introduced things), but
should be sufficient to reproduce experiments with the feature supported.
