For easier review:

Context:

However, please keep in mind that you cannot do koji builds if all of the build dependencies are not met (because you cannot provide additional dependencies to koji) and when the time comes to build these packages, they must be built in order and you must wait between builds for the dependencies to make it into the appropriate branch of the distribution.

Removed:

For the devel branch (Rawhide) this happens frequently and can be automated using chain builds, but for release branches each package must make it all the way to stable before the next package in the chain can be built.

Added:

This can be automated using side tags and chain builds.
