As we moved on to a pattern where we have multiple repositories and a host repository to collect these to merge them into one final configuration we have a lot of redundancy:

adding the input as url to the main repo
providing a module by the sub-repo to be usable by the main repo
load the module from the sub-repo in the main repo
configure the module options (from the main-repo)

This will change will help in this regard so that the sub-repo can specify the configuration as well for class in an output ${namespace}.${class} module that is automatically loaded.
So the main-repo will only specify the sub-repo as an input and automatically will load whatever is specified in that repo for the classes set for this host (by default the hostname).

So one might have a git-sub-repo fbs42:nixos/mail that has the following outputs:

fbs42.mail-server: a module that configures the @fbs42.ddnss.de mail-server infrastructure
fbs42.mail-client: a module that configures sendmail to send @fbs42.ddnss.de addresses
This repository might now be used by several hosts, e.g.
host/scarif.nix:classes = [ "mail-server" "mail-client" ]
host/ruediger.nix:classes = [ "mail-client" ]
host/kashyyyk.nix:classes = [ "mail-client" ]

automatically import ${namespace}.${class(es)} as modules 01106110fe

Allow to specify a list of classes in the host/<hostname>.nix (by
default the class <hostname> is used) that will automatically load
specified outputs of inputs.
