I'm not sure that this statement in the summary jives with this statement from the next section:
> In the previous, separate repository world, this would've been four separate pull requests in four separate repositories, and with comments linking them together for posterity.

> Now, it is a single one. Easy to review, easy to merge, easy to revert.
IMO, this is a huge quality of life improvement and prevents a lot of mistakes from not having the right revision synced down across different repos. This alone is a HUGE improvement where a dev doesn't accidentally end up with one repo in this branch and forgot to pull this other repo at the same branch and get weird issues due to this basic hassle.
When I've encountered this, we've had to use another repo to keep scripts that managed this. But this was also sometimes problematic because each developer's setup had to be identical on their local file system (for the script to work) or we had to each create a config file pointing to where each repo lived.
This also impacts tracking down bugs and regression analysis; this is much easier to manage in a mono-repo setup because you can get everything at the same revision instead of managing synchronization of multiple repos to figure out where something broke.
