I want to kill this CA. If there's anyone that sees problems with this, talk to
me and I'll see how to resolve them, as I have a plan for all the issues I
have so far foreseen.

Upload CGI is no issue as it uses http auth, so is just configuration.
I have a sigul patch for krb support that I'm going to merge soon.

Not if it's up to me.

As far as I know, yum/dnf supports setting a cafile for repos, so we
can just update fedora-repos.

I would prefer this, since that means the configuration is server-side and we
can phase over to a different CA or something at a later point in time way
easier.
