Unless the tool can pull older builds directly from Koji, I don't see
how this will work for more than a day or so. It's a cool capability,
but it seems to hinge on older builds being available, which they kinda
aren't very easily.
Reproducibility is awesome, but it doesn't replace good debug output.
For a start, you still need the useful output to debug the problem when
you reproduce it. And second, I assume building a live image is still
gonna take a significant amount of time, like 30 minutes? Typically, we
can debug a simple live image failure in about thirty seconds ("oh,
look at anaconda.log, it failed because of a broken dependency" is the
most common scenario) and probably fix it in less time than it would
take to reproduce the build.
