Should the answer be “yes”, I filed https://bugzilla.redhat.com/show_bug.cgi?id=1777377.

Building tito-0.6.12-2.fc30 against epel8 results in a tito that seemingly just works.  I'm able to do local builds and attempt to release into Koji.  Would be great to get a tagged build into epel8 officially.
