DNF and Modularity

[Miroslav Suchý]

Hi,
I have to admit that I am a bit puzzled about DNF behavior with modularity.

I have installed repo files with modularity repos, but all of them are disabled. I have no
module enabled on my system
(F29 BTW). To be precise:
  output of `dnf module list`
  https://paste.fedoraproject.org/paste/3QvX2xv4OgVVmgckTnEQcQ

And every time I run `dnf upgrade` I get this output:

It does not matter if I pass `--best` option or not.
Why I - as a user - see this warnings/errors?

Is this an error or a feature?
