That wasn't the point, though - the point was the answer the question
"why do we need *default* module streams?"
The logic is this: FreeIPA maintainers wanted FreeIPA to be a module in
RHEL, to take advantage of the added flexibility around lifecycles and
version bumps (basically so each RHEL release isn't tied to one version
of FreeIPA forever). But if it's modularized and there's no concept of
'default stream modules', this is a thing that breaks: you can't
install it from a kickstart. So, *given that* we wanted to modularize
FreeIPA in RHEL *and* we also want to still make it deployable via
kickstart, that creates a requirement for default stream modules or
something a lot like it.
This doesn't seem quite true. You couldn't install it with the same kickstart
you used for EL7, but you could use the new module command or syntax in kickstart:
module --name=NAME [--stream=STREAM]
and/or
%packages
@module:stream/profile
