Example of such an update:
https://bodhi.fedoraproject.org/updates/FEDORA-MODULAR-2019-2b5b58da12

In Fedora we will have later the requirement to gate a module bodhi update, which contains multiple module updates.

We are in process defining messages for this. We currently ignore gating of these updates, but later we will need support for them.

It is still a question how will gating/testing of such modules work, but most probably it will be similar to currently added sidetags ....
