I sincerely don't know. But how is it different from accessing the
trees nowadays and hard-coding the paths to the kernel and initrd in
the apps?
For instance, http://ftp.debian.org/debian/dists/stretch/main/installer-amd64/
isn't even available over TLS also.

So, not saying that we shouldn't care about MITM attacks, just trying
to understand how different the policy would be for this one file than
it currently is for the rest of the installer tree.

In any case, I'm more than happy to hear suggestions from the
community on how we could distinguish the installer trees on our side
if not using .treeinfo files.
