I think that for backwards compatibility, they have always had a
separate package for bind-chroot but it does make sense to always run
that way.

Also, there is a long history of attacks on public DNS servers for so
many reasons and some of that is weaknesses in BIND software but much of
it owes to the value of the target itself. If you control the DNS
server, you control the domain(s) it serves.

I don't personally see how using a different DNS server package or
running SELinux is involved with the decisions of bind-chroot packaging
