It is a question of interest really. Fedora has the technical ability
to deliver a bootstrap that happens routinely, but I don't see the
motivation to do so. Only mass rebuilds happen routinely when Fedora
makes a release (don't have bootstrap issues).

I assume you are arguing that a full bootstrap would take much longer
than the set of packages Andreas identifies. Please make such assertions
clear. I don't know if Andreas has automation to run the builds in
parallel across lots of machines and so it doesn't take that long to
add more packages.
The honest truth is that I'd like to see Python usable in the build
process for glibc, so I think we'd have to bite the bullet on a minimal
python at some point. $0.02.
