This has been tested by me on the el8.nightly. You can see the successful "edgedb-server-1-alpha7-dev5237-1.0a7.dev5237+g329b04f4-2020112800nightly.el8.x86_64" upload in https://packages.edgedb.com/rpm/.jsonindexes/el8.nightly.json. It's also much shorter now due to proper outdated package removal. Cut out 2GB from EL8, there should be a similar cut from EL7 when that runs during the nightly.
