See https://pagure.io/Fedora-Council/tickets/issue/141 and https://meetbot.fedoraproject.org/teams/council/council.2017-09-13-13.00.log... from which we came up with this request:

Modularity is an important Fedora priority, and having it be a non-sidecar option is important to Red Hat as a stakeholder. Since Modularity allows us to decouple the Modular Server release from the GA date, we'd like to take advantage of that and ask the Server SIG and Modularity WG to come up with an alternate schedule landing as an official Edition about a month later.

I know there are a lot of details to be determined, but that's the basic request. I expect we'll have some placeholder release-day content covering both "new shiny thing coming soon!" and "if you are using current Fedora Server" and possibly also "if you are using Fedora in a server context, but not actually Fedora Server Edition". (I'm personally happy to work on coming up with that.)
