Enable module default streams in the buildroot repository for modular
and non-modular RPMs.
== Summary ==
This Change (colloquially referred to as "Ursa Prime") enables the
Koji build-system to include the RPM artifacts provided by module
default streams in the buildroot when building non-modular (or
"traditional") RPMs.

== Detailed Description ==
As a major part of the Modularity design, we have a concept of default
module streams. These streams are built as modules, but the RPM
artifacts they deliver are intended to be used just like non-modular
RPMS. The aspirational goal is that a user of the system who never
executes a module-specific command (such as `dnf module install
nodejs:8`) should experience no meaningful changes in behavior from
how they would interact with a completely non-modular system. In
practice, this may mean that the informational output of package
managers may indicate that modules are being enabled and used, but a
user that does not have a specific reason to interact with the
selection of a module stream should have that managed on their behalf.
If this is the goal of default modular streams, wouldn't it be in fact much
easier to keep the default versions as urisne packages?
That means, you have 2 different workflows: for default version and
for an additional one.
When branching happens, instead of just updating one file which points
to the new default, you would have to create new stream, retire the
one which is about to become default and update package in
non-modular.
Yes. It puts additional (arguably fairly trivial) work for the modular
maintainers. Other than that, it makes lives of every other maiantainar, of the
dnf maintainers and of Fedora users easier.
I call it a good deal.
