There is another concept in Modularity we can use here: defaults. You could have both streams 1.7 and 1.8 built for all active (non-EOL) Fedora releases, but have different default for each. So in your case, F27 could have 1.7 as a default and F28+ could have 1.8 as a default.
Independently of this, you could also retire 1.7 with the end of F27 if there was no need to have it in the future releases.
Is there a way for users to say "keep me on whatever module is the default" when upgrading?
That would be a violation of the design principle that users should never have their module stream change underneath them without their consent.
Now, it gets a little trickier when we talk about upgrades from a release that supports 1.7 to one that no longer does... in that case I believe our expected behavior is that the user is expected to switch to the newer stream *before* initiating the upgrade process. So they'd do:
``` dnf module enable foomodule:1.8 dnf distro-sync dnf system-upgrade --releasever=nextversion download ```
