=== A module does not have one or more of its profiles specified to be
the default. ===
Here, I would expect that DNF will finish with error, advising the user to select a profile specifically, such as using "dnf module install <module>:<stream>/<profile>".
=== A module has explicitly set one or more of its streams to have no
default profiles ===
Here, I could imagine that such a module would be marked "special". Marking a module "special" would clearly tell QA that special behaviour is intented (empty profile or something similar). The DNF either should not list them in "dnf module list" or if listed they should have a visible distinction (such as "s") or something like that. We could utilize the difference between "dnf module list" and "dnf module list --all", that currently do the same job, so that "dnf module list" would only show installable modules, while "dnf module list --all" would list all modules, as the option suggests.
If someone attempted to install a special module, DNF should not proceed anyhow and warn about that.
=== A module has a profile that contains zero RPMs ===
See above. This should be a typical example of a "special" module.
In this case, a profile definition has been made in the module
metadata and it explicitly contains zero RPMs within it. Such an
example might be for compatibility: the module previously provided a
profile with that name that contained content, but it is no longer
doing so. Retaining the name may have been done to allow existing
scripts to avoid breaking. If we have a profile that contains zero
packages, should it be an error if we attempt to install it? If not,
what should the UX look like?
