AFAIK the only bibisect repo that you can pull from is vmiklos'

the other ones tend to get updated on an irregular schedule, and you can
only use zsync on them (at least the jlallement one) which doesn't work
well in practice to reduce the size...

thanks for providing some data to prove that given how well git repack
works the extra compression is pointless.
