I like this but I'd make some changes:

=== SCLs ===
Software Collections (SCLs) are a technology that enables one to build
and concurrently install multiple versions of the same software
components on a given system. They also have no impact on the system
versions of the packages installed by any of the conventional RPM
package management utilities. As such, SCLs will be useful for providing
various (incompatible) versions of software stacks in Fedora. The goals
which our WG has with SCLs are the following:

* Work to make SCLs usable by Fedora Products.
** Example: Fedora Cloud is a product that often depends on a specific
   version of Ruby, so it will benefit from having a means for providing
   the required version of Ruby via a SCL.
** Get SCLs into the Fedora Mainstream Repository 
*** Status: Packaging Guidelines are being reviewed and revised by the
    [[Packaging_Committee|Fedora Packaging Committee]]. Most probably each
    SCL will have a review step similar to a system-wide Fedora Change.
** Create a second repository for SCLs that do not following Fedora
   Packaging Guidelines
*** Cooperate with the SCL Upstream on enabling Fedora users to install
    and use the SCLs provided by the SCL Upstream. This will extend the
    number and diversity of software stacks available to Fedora users.
**** Status: SCL Upstream is almost finished and ready for launch.  Need to
     work with FESCo, SCL Upstream, and write code to make these
     repositories easy to enable
*** Work with FESCo to see if we can make some subset of those repositories
    direcly installable by the Fedora Products.
*** If not, then figure out if we need SCLs that are not Fedora compliant
    that are directly installable by the Products.

[sclutils section would remain as you wrote it]


Regardless, I don't see anything wrong with the section as written in the
draft; it's just not as detailed as to the strategy to take as this is.

+1
