I *think* comps entries with no explicit 'type' default to being treated as 'default', not 'mandatory', and dnf is considering it to be OK if a 'default' group package cannot be installed. After looking at the references, I'm pretty sure this is not how yum behaved. I don't know offhand why this behaviour was changed in dnf.
Then we'll need to add type="mandatory" to absolutely everything, because we always want compose to fail if a package is missing.
