The `environment.cosmic.excludePackages` option was used to exclude some
packages from the environment which also includes some packages that the
maintainers of the COSMIC DE deem necessary for the COSMIC DE to start
and initialize. Excluding said packages creates a high probability that
the COSMIC DE will fail to initialize properly, or completely. This is an
unsupported use case. If this was not intentional, please assign an empty
list to the `environment.cosmic.excludePackages` option. If you want to
exclude non-essential packages, please look at the NixOS module for the
COSMIC DE and look for the essential packages in the `corePkgs` list.
You can stop this warning from appearing by setting the option
`services.desktopManager.cosmic.showExcludedPkgsWarning` to `false`.
