It is currently only in rawhide, but the idea is to migrate it to the other
releases as well.

There were various problems with the chroot. For one, there is the issue of
updated DNSSEC keys (via dnssec-keys and autotrust). Then there is the issue
of package updates and the --bind mounts not getting unmounted in time for
the package to do an update without causing problems in the scriptlets.

And last, with the coming of instant cheap VM's for a single purpose (eg
nameserver) the concept of chroot's is becoming rather useless. The only
value content of a VM running a nameserver is within the chroot itself.

I can see about adding an option for chroot building in the spec file, and
having it disabled per default, so you only need to rpmbuild the source rpm
with a --define 'use-chroot=yes' but I'd still prefer to just completely get
rid of it.
