Yeah I'm surprised by that as well. As far as I remember, Rosie started out in 2010 and people were using in 2012. Maybe the clustering/splitting didn't support this use-case or it wasn't well-known enough?
From my memory, extremely large but semantically simple changes still used global approvers since it wasn't considered worth the effort to get approval from hundreds or thousands of individual OWNERs using rosie. Also, with a change of this magnitude, especially one affecting BUILD files, it might not have been possible to create the mega-CL that rosie uses, but I don't remember specific limitations on that.
That's exactly what I remember. I did a few LSCs; one I used Rosie just to see how it worked (I recall wanting to use it for all my CLs because it submits after someone clicks approve and the tests pass), but most of the time it was easier to find a global approver and submit the whole thing atomically.
